Well... it confuses me!
No, seriously, I don't find the WP revision system particularly intuitive or useful. I'd rather have something more like a simple version control system that required me to add a log entry ("fix typos", "rewrite intro") and then next to each revision had a "delete" and a "revert to this version" button.
But I can't help you out... don't know of any such animal. If you build something, let us know!
