I am the only referee that I know who actively looks for this.
In the lift above, I probably would have given a white, but since I am also a coach, I would probably have a chat with him after the competition, since it will limit his lifting to a great degree.
It is (usually) really hard to see if the bar actually comes to a full stop, so it's a judgement call. I've never given a red for it in the snatch. A few in the clean. Usually, it gets worse the closer the lifter gets to his or her max.
