Why does this happen to me? :)

The big thing to remember is when the arrow changes and why the ball is being put in play. The arrow changes when the ball is released on the throw in. So in case "A" The arrow cahnges when the ball is released and then put back into play as a result of the OOB. If a foul occurs before the release, the arrow does not change, but the reason the ball is put back into play is then because of a foul, therefore the arrow does not change. Not at all confusing when put in that perspective.
