The key with the definition is, if time expires prior to the ball going through the "wrong" basket, it doesn't count. Same if there's a foul on the "shooter" at the wrong basket. Ball is dead, and the player is not considered in the act of shooting when he's fouled. Ball out of bounds for a throw-in unless the bonus is in effect.

I'm not aware this differs at any level.

This is true at the NFHS, NCAA, and NBA level.
