I'm glad folks are finding this interesting. However, this is pretty much common knowledge to anyone who has taken music theory. It's usually not given a great deal of attention as most musicians using the standard 12 tone don't care much about what's going on under the hood. They're a bit like programmers who use a high level language and an IDE and don't know how a compiler or assembly works.
Just a bit funny to come across it here, it'd be a bit like finding out musicians were talking on a forum going 'wow, computer programs are written using structured text files!' or something of the like. Not trying to be rude..
My advice if you haven't read the article -- skip it.
