The tail, unlike the remains of the front part of the fuselage, is still intact and not restrained by friction with the ground. Therefore of course it's momentum is going to carry it ahead of rest of the fuselage.
Essentially, this is the same effect that you get when lifting off the throttle in a front-drive car when going down a steep icy hill. The front is restrained and the tail wants to over take it.
