Maybe this should help:
2-27-6-b
b. An airborne player is a player not in contact with the ground because he leaps,
jumps, dives, launches, etc., in other than normal running action.
When he is in the air because an opponent hit him (involuntary), he's not an airborne player by definition, so 4-2-4-d exception doesn't apply, when the play declared dead is between goal lines.
When goal line is involved, the situation changes with 8-2-1-a, so the example in bulletin in 2009 will be no longer a TD, but rom gilbert 2015 example will stand.
A.R.8-2-1-VI-b
Ball carrier A22 heads for the right-hand pylon at the goal line. At the B-2 he dives or is blocked into the air by an opponent. The ball in A22’s right hand crosses the sideline at the B-1 and passes outside the
pylon, and then A22 (a) touches the pylon with his foot or left hand; (b) first touches the ground out of bounds three yards beyond the goal line. RULING: (a) Touchdown. The goal-line plane is extended since
A22 touches the pylon. (b) Not a touchdown. The goal-line plane is not extended because A22 did not touch either the pylon or the ground in the end zone. The ball is ruled out of bounds at the B-1.
Kalle, I don't get your point. If the ball passed outside the pylon, it should have crossed the sideline. So with 4-2-4-d we put it back there
