WordPress Editor Generates Page Title Links From Pasted URLs

Noting that if I paste a URL into my WordPress.com visual editor, behind the scenes it can look up the link, pull a page title back, and create a link using the title as link text and the link set to the URL I pasted in:

I’m not sure if this requires any particular metadata on the page referenced by the link? Certainly, it doesn’t seem to work for every URL? But then, Pete Warden’s blog – what do you expect?!;-)
