What people don't realize is with jump you're actually sliding up and down terrain as well, just with a different animation. Your position is being tracked which is sliding up and down the axis when you jump onto and up cliff faces. This is why if you jump you can notice that your character "pops" up higher while in mid air if you jump at a correct point that puts you onto the cliff face. This happens in quite a bit of even offline games.

What they did here was just take out the jump animation portion of it, but the mechanic is in essence the same.
