Is this play wrong, then? And why am I on the strugglebus about this tonight?

Play # 5: "A1 has the ball for an endline throw-in in his/her frontcourt. A1's pass to A2, who is standing near the division line, is high and deflects off A2's hand and goes into the backcourt. A2 is then the first to control the ball in A's backcourt. RULING: Legal. There is no violation since player and team control had not been established in team A's frontcourt before the ball went into Team A's backcourt."
