Experimental Adsense Format?

I just came upon the Adsense format below:

Three text links appeared below the regular ad unit. If you mouse over the text link, I find the link to be in the format of ‘javascript:gurl(‘XXXXXX…XXX’)’. I used Google Blogsearch to see if anyone has noticed this type of display, and didn’t find any mention. Wondering if Google is testing a new Adsense for Content format that combines an ad unit with a link unit?
