When it comes to Google, it's very trendy today to be cynical - even The Onion [theonion.com] is in the mood.
In this case, I don't think there's any such sideways motivation. No SEO is going to share a trade secret with Google, and the rest of it you can learn about at any of the public SEO conferences. What I'd say is it is an ingenious way of spreading the word about SEO basics to a world that is far from understanding them at this point.
