I have similar experience with Yahoo's directory results appearing instead of the actual page's current description and content. There are cases where the keyword that applies to a homepage shows up on page one, but shows the original directory description and title. Somewhere around page 2 or 3, the homepage is listed again, but appears as it was indexed during the last update. I haven't seen them closer together though, as you are experiencing. Perhaps it's good for your site though, great to secure #1 and 2 spot.
