Several players like this option ON as they do not trust their opponents. With long games you would have to redo the entire move. Some folks that cheat will do part of a move up to the part where a critical attack will be made. They will save the file and then redo the attack until it comes out to their liking.
An unsavory way to play for sure but that is why some folks turn it ON.
In this club I would never use it. In others .... well I can think of one club where I would use it for most of my games.
