I just discovered this odd behavior of Mail and Safari. If you perform a find (command-F) in Safari then switch to Mail.app and filter a mailbox by a term then back in Safari you use the find again command (command-G) the term you filered by in Mail is used.
Very odd behavior but it looks like these to apps are certainly targeted for even more integration.
