I don't think there's any violation for the mere touching by A2 if the ball is past the plane. The touching by B1results in a held ball
6.4.5 SITUATION B:
During an alternating-possession throw-in, thrower A1 holds the ball through the end-line plane and B1 grabs it, resulting in a held ball.
RULING: Since the throw-in had not ended and no violation occurred, it is still A's ball for an alternating-possession throw-in. (4-42-5)
