How is he doing that

When he steps down it adds and angled pressure to the bottom most part which would normally cause it to pull away from the tree, yet since the top is looped around the tree then the force gets distributed inwards towards the bottom and on the back with the loop. When he steps up he removes that force allowing the loop to go slack again so that he can raise it once again.
