Here's a similar play:

2011-2012 NFHS Basketball Interpretations

SITUATION 5: A1 has the ball for an end-line throw-in in his/her frontcourt. A1’s pass to A2, who is in the frontcourt standing near the division line, is high and deflects off A2’s hand and goes into Team A’s backcourt. A2 is then the first to control the ball in Team A’s backcourt.

RULING: Legal. There is no backcourt violation since player and team control had not yet been established in Team A’s frontcourt before the ball went into Team A’s backcourt. The throw-in ends when A2 legally touches the ball, but the backcourt count does not start until A2 gains control in his/her backcourt. (4-12-2d; 9-9)

I think this play is similar but the biggest part that is missing is the division line is erased for the person who first touches it only. So I'm not so positive that the original OP is legal. Of course, I don't have my book in front of me now.
