Yes, the upper pin has the bushing and the lower pin does not. The first time I re-did the brakes, the pins with the bushings were in the bottom. I don't know if I screwed it up, and why they were glazed the first time, but that's where they were. So I actually put them back in the bottom and then put new brake hardware (caliper clips) in the Honda that afternoon. I noticed the pins with the bushings in the Honda were on top. So I logged-on to Alldatadiy.com and found that the top is the correct place for the pins with bushings on BOTH cars. So after I finished the Honda, I went back to the Acura and swapped the pins. But I never re-finished the pads or scuffed them up. I got a lot of brake feel back in the pedal with the bushings where they are supposed to be, but I may have sabotaged that brake job by not sanding those glazed pads down.

It's very easy to mix the pins up. I dislike the different pin design. I always end of forgetting for sure which one goes where and that the bushing goes on top.
So you think maybe the pin being in the wrong spot may have contributed to the uneven rotor wear this last time or did you switch them before any brake use and wear? From what I can tell it sounds like you corrected the pins the same day. If that's the case then the pins probably didn't have time to cause uneven wear.

I had to re-cut the rotors once before due to the very same glazing issue. It was then that I discovered that the pins were in backwards. The service manual does say that if they're installed wrong, it can cause noise, sticking calipers, etc. I figured that must have been the cause. Anyway, I re-cut the rotors but re-installed the pads without touching them. That was about a year ago I'd say. But yes, I did correct the same day...before I even drove it, so there actually was no drive time on it. But they were installed backwards from the factory I think, so I'm not sure if it really had much of an effect anyway.
This last weekend, I affirmed that the pins were installed correctly, but did note that one of the pins (the one with the bushing incidentally) on the passenger side was pretty sticky. Not dry, but sticky. I could not pull the pin out of the caliper mount myself, but could pull it out after threading the bolt in a little ways. I cleaned it out real well, and use the purple Permatex. Honestly, that felt just the slightest bit tacky as well, but the pins did slide easily. And I affirmed that once installed (with no brake pads), the caliper does slide easily back and forth. This time, I re-cut the rotors AND installed new brake pads. Hopefully, the problem only returned again because I put some bad material from the glazed pads onto the freshly-cut rotors...and/or because one of the pins was sticky.

I think I got it. Maybe the pins being in the wrong position caused the original problem of uneven pad deposits. And you corrected the pin postion a year ago but reusing the pads untouched may have led to the uneven pad deposits or wear.
It does look like a pad issue and not a rotor issue. Maybe the B/A pads weren't really OE quality. I'd say with the OE Akebono pads and the pins squared away, that the pads have completely been taken out of being suspect. So if the problem returns it would point to the rotors or maybe not a smooth enough machine finish. I don't think the rotors are the problem or that the problem will return though.

That's my opinion as well. I think that there is a good chance that if I scuffed/sanded the pads real well last time, the problem may not have returned. I was expecting the Advics pads to be good quality pads. And they may have been; it could have been this shadetree mechanic that ruined them.

How are the Akebono pads performing?
So far, they're performing well. But the pattern here seems to be that I don't have any issues with it in the cooler months, and get this rotor glazing in the summer. I'm not disappointed at all in the Akebono pads (at least so far). If I get glazing again this summer, I'm putting on different rotors.
Just remember if the rotors are properly prepared and everything is correct then you are experiencing a pad/caliper issue, not a rotor issue.
Normally most modern pad formulas on stock non-performance oriented autos are not going to do anything but polish the rotor to a gleaming shine. You won't get pad transfer unless you drive very aggressively and brake hard from higher speeds.
