Asking the wrong friend?

Just caught these millionaire clips. Not a big fan, in general, (prefer Jeopardy) but I have watched a few episodes. But what I thought was most interesting was when he went to phone a friend, and showed his three friends. Was the third one, the Dan from Cambridge, the same Dan from Cambridge who won his semifinal round today (well, ok, it was shown today; I don't know how long the tape delay is) in Jeopardy's Tournament of Champions? Sure looks like him, but I'm not very good with faces, so I'm not certain.
