I believe it is the little backwards movement the "head"
makes when it starts to read a chunk of image.

It is kindof like 2 steps forward one step back. My
understanding of why this happens is to ensure that none
of the image is missed between chunks.

I hope you weren't looking for a technical description. :^)
