There was some discussion about an OOP (over optimisation penalty) a while back and I am one of those who subscribe to this. It may be that the same words in domain name, page name, page title, page description and H1 could be a flag to indicate that a site has been created solely with SEO in mind. And when you think about it, it would be a pretty good flag ;)
