Why does the article say there are 2^N different possible configurations? Shouldn't it be N! ? Maybe I'm missing something, but I don't see how they can rule out so many different orderings of the "configurations", since he started out by saying that the ordering wasn't reliable.

Edited: I figured it out. It's because they essentially do a binary search of the changes to find the issue, I should have read a bit further before commenting. The tables / examples cleared it up pretty quickly.
