Correct Possession procedure or not???

[Redhouse]

I thought that the throw in by A-1 ended with the violation, so team B would have the next throw in under the APP. When B is awarded the ball for throw in the arrow would be switched to A for the next APP. Just remember if you do screw it up and either of the coaches complain just tell them tht you will give them the next 2 out of 3 held balls.
