I have seen similar. If you get a snake that has been very stressed, not eating, and has damaged skin... once you correct the husbandry and get them eating with consistency you will get a few back to back sheds, but slowly they will taper off and she/he will assume a more normal schedule.

Even the rate of shedding... from turning blue to sloughing their skin seems to be advanced... a few days vs. a week.
