Again, it is already moving upward as you can see in the photos so contracting the traps upward will not do anything to make the barbell move upward especially if the lifter is already moving downward.
When referencing moving backwards I meant the feet will jump backwards about an inch or so or move no where at all would be most disirable to lifting heavy weights. Some do it by chasing it, most notably Taner Sagir, Reyhan Arabacioglu, and Oleg Perepetchenov, but just because they do it doesn't mean I would teach it that way.
We agree that when lifting those weights and when you are a lifter of that level it is not a pull-shrug-squat, what I am suggesting is that in order to obtain that in the first place, optimally it should be taught as snatch/clean instead of pull-shrug-squat. I do think quite the oposite as you though that is possible to lift those weights without the shrug and by shrug I mean actively trying to pull the traps to the ears after the bar has brushed. Again, it is already moving upward as you can see in the photos so contracting the traps upward will not do anything to make the barbell move upward especially if the lifter is already moving downward. The shrug can be thought of as a stretch-reflex action from the extreme weight pulling down on the arms, stretching the traps, then after the lifter brushes and jumps under the bar the shoulders move up as a result of the stretch taken off of the traps as well as the elbows beginning to rotate around. It is much the same effect that the hamstrings experience during the pull. In the end he makes a speedy transition from moving up to moving down and it is one perfect fluid movement totally indistinguishable from one another. This is where we are lacking big time in US lifting as a whole.
