I beg to differ. To complete a catch a player must secure control of a live ball in flight with his hands or arms before the ball touches the ground and touches the ground in bounds with any part of his body. Then maintains control of the ball long enough to enable him to perform an act common to the game (Rule 2-4-3-a-1,2,3,). When the catching process was completed, the player was out of bounds and thus is a KOB. Great call!
