Great observation! Well, the jacket and the sweatshirt match part of the episode, so I guess it must be a deleted scene. It looks like Reese is keeping a suspicious eye on Hal's obsession with the dominoes, so that's another reason it's probably part of Cliques. I guess it was superfluous to the action. Thanks!
P.S. These photos are from the pre-fully-digital era, so there are no metadata (embedded picture tags) that give any clue when this scene was filmed in relation to the other ones.
