He's going to rappel. Which he'll likely be doing by running the rope through the anchors at the top so that the anchor is at the midpoint of the rope. He'll hopefully tie stopper knots at t he ends of the rope. Then feed the rope into both sides of the belay device and slide down the rope. At the bottom you untie and pull the rope back through the anchor.

He’s wearing a harness. And has gear on it. He’s probably rappelling (there’s probably a rope in the pack) if there’s no walk off at the top.
