The ball is out of bounds:
b. When it passes over a rectangular backboard.

7.1.2 SITUATION A: The ball strikes the side edge or top edge of the backboard or passes over the top of the backboard and the ball: (a) came from a throw-in from behind the plane of the backboard; or (b) from a pass or try from the front or back of the plane of the backboard. The ball does not touch any supporting brace.
RULING: If a fan-shaped backboard is being used in (a) and in (b), the ball remains live. If a rectangular backboard is used in (a), the ball remains live after touching the side edge, but it is a violation if it passes directly over the backboard. In (b), the ball remains live if it touches a side edge or the top edge if it rebounds and comes down in front of the backboard. The ball becomes dead if it passes over the top of a rectangular backboard regardless of the action which causes it to pass over or whether it comes from the front or back of the plane.

That is my conflict. The ball did not come down in front of the backboard
