I hate that I agree with Brandel. The eye test is obvious that it moved. Without slow motion and super zoomed in it moved. I don't think he got any benefit from it but it still moved. Should of been a penalty.
I thought the rule was the ball was allowed to move, if it came back to its original spot. I think though, the rule says you should not be intending to improve the lie. Close call on that one, but if I'm a player, I'm just not grounding it so close to the ball, who knows what can happen there, why chance it. Especially in that scenario when it was a punch out anyway, why risk it..the ball moved so it's a penalty Imo. You typically see the pros test the ground away from the ball to make sure they don't move it. This is no different than trying to move a rock or leaf from around the ball without moving it. The ball moved so penalty should have been assessed.
