Resetting hop up?

After playing this past weekend with some buddies of mine, an interesting point got brought up between us. As we were packing our gear at the end of the day, I noticed one of my friends resetting or undoing the hopup on his gun(or back at normal position with no hop). I asked him why he was doing that and he said because it's better for the bucking so it doesn't remain stretched, and keeps it "form". None of the other guys said they do that and nether do I, neither have I heard of someone doing it before.

So just out of curiosity, does anybody reset their hop to normal position after play?
Is it better for the bucking?
