It sounds like there might be some structural issues (asymmetrical, popping jaw) and perhaps some neurological ones. The neuro issues can certainly be caused by pain, which disorganizes and dysregulates babies; or the sucking issues can be caused by a minor neurological problem, which leaves the baby a bit hungry, which increases the dysregulation. Mom is observant, the excessive lip movement is compensatory, and when baby is more "together" he can do a better job with his tongue and does not need the lips as much. The sliding down to the nipple bothers me, I almost always see this with those sneaky posterior tongue ties, or a short mandible that changes the relationship between the jaw and frenulum. Sometimes you can't see anything, until you slip a finger under the tongue and lift it. With a posterior tongue tie, some babies improve markedly between 6 and 12 weeks, even without intervention of any kind. Some continue to cause pain until treated with frenotomy.
