Inbounder touches deflected pass

[ballgame99]

Had this scenario come up the other night; A1 is inbounding the ball and it gets deflected by B1 (who is in bounds, so no plane infraction) back towards A1 (who is still OOB) where it hits A1 on the knee. I call the ball out on A and give the ball to B. At half my partner asked the question of whether A1 had to establish himself on the court before it could be out on him. I didn't think that was required, and my reading of 7-1 and 7-2 doesn't seem to show any such requirement. Am I missing some exception somewhere?
