RR: One important point to keep firmly in mind: Article 4 is titled "Out of Bounds at Forward Point," which means that everything that follows refers to a player going out of bounds.
A22 has the ball at the B-2 when he voluntarily goes airborne and the ball in player possession breaks the plane of the sideline at the B-1. Before contacting anything else, the ball still in player possession touches the right side of the pylon (the side away from the middle of the field).
RR: Touchdown. The pylon is in the end zone out of bounds, so the player has not gone out of bounds before going into the end zone. Article 4 does not apply.
