It is actually different. In terms of relative, linear velocity, it is correct that the nearest part of the core to a particular point on the surface, it is moving backwards, but then the furthest part of the core from that point is moving in the same direction. The aggregate motion of the core linearly relative to the any point on the surface is zero, so it is not even the core that can be said to be moving backwards. Moreover spinning is angular velocity, not linear, and it is not spinning backwards, it is spinning the same direction, just not as quickly.
