What is google doing? Strange SERP’s

Initial Disclaimer – yes I am vane. I was doing a search for my name, to see where I apear in the rankings for a fairly common name (page 2 – woohoo!) however the results come out looking pretty strange. There are two inital catagories, including one that has a sublink labeled “See results for ross johnson nabisco” with only websites related to Nabisco’s Ross Johnson.

Trying to simulate this result, I spent about an hour searching for names or combinations that might also reproduce this effect but found none.

Very strange, here is a screenshot.
