Related PPC Ads in Sponsored Listings

I was wondering if anyone else has noticed "Related To" sponsored listings?

I'm taking it this relates to the amount of searches that a certain keyword gets, or the CTR of a given keyword?

If anyone has any information on this would be welcomed...

Here's a link to an example:

I found some information about it on TheSearchAgents [thesearchagents.com] - it includes a pretty detailed reply from their Google representative"

We've recently enabled a feature on English language versions of the Google search results page in which additional advertisements for related queries or refinements of the user's original query may appear...

Ads that appear under these refinement headers are targeted based on relevant broad match keywords in an advertiser's account.

A few more details from Google appear in the article, but this is apparently the crux of it.
