Guitar Balance Technique?

[Earth Breather]

I have noticed a lot of players when playing solo's have their pinky resting on the far side of the guitar, does this give more balance?

Taste. It helps when muting and gives more control, but I find it to be too cumbersome to really work. But michael angelo does it...

same here, I think they refer to it as anchoring, helped me in the beginning to know the position of my picking hand especially when playing fast and skipping strings, now it just became a habit
