OK (not OT) - here's my guess

This covers the situation where A taps a throw-in into the backcourt...if there wasn't that article, then that play would be a backcourt violation as all four criteria would be technically met. This exception doesn't apply in your case because A2 has caught the ball thus player control has been established.

Got it. Thanks.
