This is an interesting approach and I can see the benefits for non-fiction books, as many of them have a certain degree of "fluff" anyway you want to skip quickly. It does seem a technique that is more suited to physical books though, I don't see myself easily skipping to and back on an e-reader, but maybe I'm doing it wrong.
