pattern_is_full: you're right, I'm wrong. Musta misheard it.
Anyway, the key point I wanted to make is that the recording in question is incomplete, and no doubt there was some observation after landing that AS27 was on T, not 16C; but since the feed gives priority to EAST, instead of that discussion, the recording has Delta 2210 lining up on 16L with a passenger going to the bathroom.
