Jump Ball Violation

Okay, here's a situation that I thought I knew, but now you guys may have me confused. Assume NHFS here.

Second, if A1 taps the ball while the ball is on its way up after leaving the Referee's hand(s), A1 has committed a jump ball violation. Both NHFS and NCAA say the Team B gets the possession of the ball for a throw-in nearest the spot of the violation and the arrow is set towards Team A's basket when the ball is placed at the disposable of Team B for the throw-in due to Team A's violation.

Okay, so you switch the arrow as the player has the ball at his disposal? I thought that you always wait until the throw-in is complete or team A commits a throw-in violation. I know it seems the same, but take the case of a T. If B commits a T before the thrower has completed the throw-in, then A gets two shots and the ball. Furthermore, at least per NHFS, they should also keep the arrow too, since they never realized the privilege of having the AP arrow going their way.

Am I missing something here?
