You can do it that way, but you're going to get a lot of garbage from the bottom of the pan. It's not "wrong" to do so, but it's not the convention and it may skew the results that they base their UAs on, which in turn gives a slight bend on your view point.
Do it the way they suggest. Or, get a Fumoto valve.
The way I do it is that I let the stream run for about 5-8 secs, then I tip the bottle about 45 deg and put the mouth of the bottle only partially into the stream, catching a percentage of the oil as it escapes. I might get 30% of the stream into the bottle, and the rest continues to the catch pan. This has the effect of being less messy, and also spreads out the capture over a larger sampled capacity.
