B2 jumps from his/her frontcourt, catches the ball in the air and lands in the backcourt. RULING: Backcourt violation on Team B. The throw-in ends with B1's deflection (legal touch). When B2 gains possession/ control in the air, he/she has frontcourt status. A backcourt violation has occurred when B2 lands in backcourt. (9-9-1; 9-9-3)

As far as I know that ruling hasn't changed, and since NFHS told us last year that we called backcourt plays as we have before even w/o team control added to the throw-in, I think the OP's play is technically a backcourt violation.

It seems that the case play and rule as written are contradictory on this scenario. Isn't B still on defense in this play? Even thought the throw in has ended because of B1's tip, B is still on defense as A still is in team control. B2 secures the ball in the air and lands in the backcourt.
Article 3 states "During a jump ball, throw-in or while ON DEFENSE, a player MAY JUMP HIS/HER FRONTCOURT, SECURE CONTROL OF THE BALL WITH WITH BOTH FEET OFF THE FLOOR AND RETURN TO THE WITH ONE OR BOTH FEET IN THE BACKCOURT. the player may make a normal landing and it makes no difference whether the first foot down is in the frontcourt or backcourt.

What am I missing?
