If the covering official is on his game he will ensure the spot of the foul (even by moving his flag) is not that close either way....:-)

But why sweat that, when determining the spot the passer lost possession of the ball is so imprecise? Does the passer have possession as long as his passing hand is merely touching it? There's got to be a certain point in the throwing motion where the only control the player has of the ball is aiming it a little, and the player couldn't actually do anything else with it but release it; is it still a "run" at that point ("held or controlled")?
