It takes a while especially on a high filter for the oil to drain out through the main bearings. If I drain it all night nothing at all comes out of the filter. It depends on the hole size, viscosity, and the density of the liquid. Try the dining table test. So when the Camry is started every morning cold the center tube has to fill back up. Without any doubt. That's why I never used the long version 3600 on it. Maybe you have the magic engine so tight nothing goes through the parts back to the pan, ever.
I did do the "dining table" test on a PL14459. It sat for a whole week and the oil trapped between the media and can never leaked out the center tube.

All I can tell you is that I know for a fact that the center tube doesn't drain on my Tacoma because if I remove the filter even after the truck has been sitting 3~4 days (which I did test out one time) the filter still pukes oil out the center tube. It might depend on the oil galleries geometry is designed on various engines, which could factor in how oil might drain back or not.
But in any case, if the ADBV is not sealing well, it will most likely drain back on both sides of the ADBV. So did you check to see if the space between the media and can was also drained out of your filter? If it was also drained, then the ADBV was probably not sealing 100%.
