Umm, almost. The arrow doesn't *change* because it hasn't been set yet. Placing the ball on the floor (for B) *sets* the arrow. The fact that a TO was called is important because it allows us to use the resuming of play procedure, thereby placing the ball at the disposal of team B (on the floor), thereby setting the arrow for team A.
Someone please correct me if I am wrong, but if during the game we have a held ball, and we're going with the arrow showing A, and A takes too long, I believe it's a warning for delay of game. The reason it is not a warning in my example, is because we're using the resuming of play procedure.
But, during the game and using the arrow, the arrow changes when the throw-in is completed. A throw-in is completed when an inbounds player legally touches the ball, or the throw-in team commits a violation.
