Interesting throw in play

[johnsonboys03]

A1 scores a basket and her momentum carries her oob. While A1 is oob B2 picks up the ball oob and attempts a throw in. A1 still oob knocks the ball out of the hands of B2.

I'm sure as long as the ball is still on the oob side of the boundary line this would be a violation of the throw in provisions which results in a technical foul and a team delay of game warning.

My question is if the ball was on the in bounds side of the boundary line, would this just make the ball dead and become oob by team A and team B would be awarded a throw in again at the spot?
