Take a look at a Brooks saddle,or any old timey type saddle,there is a big fat brass rivet on the tip of the nose. When we push hard we end up forward on the saddle. Thus, on the rivet. My theory is that muscles are made to contract , any and all looseness in any joint disappears under all that contracting.and our feet come up to maximize stability for the effort. Our arms tighten and we begin to pull on the bars. I think we just slide forward to compensate naturally for this temporary change in our fit and to focus our energy better. If you are rocking a lot, I would lower your saddle 1/8th inch and try it again, see if it gets any better. You can always move it back if it doesn’t help.
