I just watched the play, and here's my $.02. The A player leaps from the field of play and touches the kick while he is still airborne (the touch is legal, since the ball has gone 10 yards, and it has been touched in bounds since the A player has not "established himself" OOB by touching the ground or anything else OOB). So it is not a KOB. Possession is not established until the player controlling the ball comes to the ground, and he comes to the ground OOB. Therefore, A does not get to keep the ball since they did not recover it in bounds. No foul and it's B's ball. Chalk another on up for RR.
