Glenn - jumping back in the snatch or clean? I’ve seen numerous elite lifters do this, Marcin Dolega is one of them. What’s the deal?
Don McCauley has a way better thought out response to this than I do… I am gonna ask him to jump on here and answer yo…

Andy,
Thanks, Glenn for writing to me about this. Hi to everyone on this forum. Just looked at a few threads and like the conversation level here.
Andy, you know all about the “S” pull if you’ve been on this forum for very long. The jump back has to do a lot with leaning that S to the rear. The reason for doing that is to better keep the bar over the starting base of support(at Set)and “skinny” the S, and to help the lifter get to the catch position more quickly. The reason these things happen when using this pull is that lifters are continually driving the bar more towards them(and rearward), even during the slight forward bulge of the S in the 2nd pull than in a stright up and down S. If you’ve ever toppled and stumbled backwards, you’ll notice that the rear of the feet get down more quickly to prevent a fall and the posterior musculature is engaged more directly and quickly to stop the fall, rather than the quads. Those same things should happen when you go to a squat for the clean or snatch. It helps some lifters get to the proper flat-footed catch position more quickly and it certainly prevents the bar from being too far out in front at the catch. And, as you observed, it causes them to jump back a bit to catch the more rearward driven bar.
And, because the bar is accelerated upward by a combination of the knee and hip extension, when you tilt backward the hips are not only more likely to be fully extended but the direction of the extension will be more towards vertical(you’re pointing them upward as you tilt back), which happens to be the way we want the bar to go. Additionally, the lifter can more easily stay over the center of his base when driving the bar, which is also good.
Now that I’ve got you really confused, look at it this way. A normal S pull comes in towards the lifter (and further back into the original base of support),then out away in the 2nd pull and then back in during transition and catch. Tilting the S to the rear keeps the bar traveling more toward the lifter and in the center of the original base of support without any more work (maybe less) by the lifter because all he is doing is continuing the general bar trajectory that was started in the 1st pull(in towards him), if it was done correctly.
Another result of this seems to be(I haven’t got data, only observation) that the pull (drive) is faster! It seems like the drop-off of force at the double knee bend is less or the time to accomplish it is. I don’t know which. But, it is a fast pull(drive).
Some lifters (Dolega seems to be one) start this whole tilting thing off right from the floor. They seem to be contiually moving to the rear. Some seem to make a pronounced exagerated effort to the rear at the end of the double knee bend when they go to their forefeet, by driving back hard from that raised position, almost like a plyo jump back off the forefeet. Different methods of accomplishing the same thing.
If you have any questions, I’ll be posting here more often and will be glad to respond.
