Correct.
Also, can the search engine distinguish between the code in the post or tagline? I wouldn't think so.

Unknown, although it was structured that way in the example that I saw. It might however, explain to other posters why one keeps putting links to Moore's site in their posts. And, it couldn't hurt.
