Not really absurd at all, one of them has to actually catch the ball whereas the other already has posession. If this would have been incomplete anywhere but the end zone it should be incomplete here.
You're basically comparing a fumble to an incompletion
There was that game against the Panthers on MNF or maybe SNF a couple of years ago where there was a possible PI call at the end of the game and Brady was screaming at the refs on his way off the field.
