I’ve installed [Mac OS X 10.7][lion] (upgrading from 10.6) and was very interested to see how the new search tokens feature would work in Spotlight. But on my Mac it doesn’t. Here’s the result of a search for files whose name contains the text “david buxton”:
Note how none of the files in that list has a name containing the text “david buxton”.
Perhaps deleting the Spotlight index would fix things. Meh.

If David Buxton is your username then I’m wondering whether it’s picking up your name from the path or from some creator/user metadata.
