Test ? # 81 (NFHS)

[xxssmen]

Once the ball has been released by the thrower, opponents may break the throw-in boundary plane.

I said false and other officials say true.

We found the ruling in the rule book under rule 7-6

Art. 3... The opponent(s) of the thrower shall not have any part of his/her person through the inbounds side of the throw-in boundary plane until the ball has been released on a throw in pass.


Now after reading that I am confused.

Example: Team B just scored a baskets and A1 attempt a throw-in but couldn't before the 5 second count is reached A1 request a time out.
After returning from the time out inbounding official tell A1 he still has the baseline if he needed it, A1 start his throw-in and decide to throw the ball to A2 who came in from the inbound to out of bound and than pass it to A3 all before the 5 second count has ended.

Based on the ruling in 7-6-3 than is it legal for B1 to reach and break the plane to intercept the pass which has been released from thrower A1 to A2 while they are out of bound?

Any input on this ruling will be appreciated.
