Another question ... What happens if the attacking player is before the final line but there is no other teammate in the final line to pass him the ball? As you see, there is no attacking player in the destination line to count. Is this considered as a failed attempt or the ball stays where it is?
This is still a valid pass, so you normally pass the ball forward and lose it in the process. When you play a long ball, you must choose a line with your players IN THE FIRST PLACE, but if there are none, you still must pass the ball forward – the attacker simply did not make the run. Btw, in this situation, always check if SNAPSHOT is an option as it is always better then losing the ball.
