United States/Stamps : Question about Nebr. and Kans. Overprints

There's a note in Scott's that says that original mint copies of these stamps have either one or two (separated) "gum breaker ridges" on the back. They have to be there for the stamp to have original gum or not be a fake overprint. I have a few of these stamps in mint condition and some of them do seem to have the required ridge(s). Some US stamps, from what I read online, have multiple ridges - these overprints must have one or two. Has anyone made a study of this to the point where you could give me a simple explanation?
Addition: I just located this amazing little article that seems to explain things very well. http://riversidestamps.com/KansNebrFakes.shtml
I'm sorry, my next link was supposed to be live, but I haven't practiced yet!

The APS put out a 35 page booklet on the Kansas-Nebraska overprints. I do not know if it is still being sold.

If by "simple explanation" you mean, why did they do it, the gum breaker ridges were a new feature to prevent the sheets from curling up. Any Kans/Nebr overprint on an earlier stamp without the ridges is automatically a fake. I would focus more on the overprint itself, though, if you are trying to detect fakes. The articles quoted should help out!
