Not at the end. If you look carefully the eye is NOT centered on the image at the end of the loop, it's moved up!



Actually, it hasn't. What is happening is the eye has become completely obscured. You're looking at a swirl of clouds over the eye that is rotating around the actual eye (almost on top of it actually). The move "north" is simply the illusion caused by the counter-clockwise rotation of central cloud the spiral.

Its hard to tell on the a storm-centered IR image, but the Visible shows it well. You can see the cloud rotating around a central point. If you use this visible CMISS link you will see what I'm talking about.

EDIT: Bad reference graphic. Fixed for the Visual one which I was talking about this time
