As in look more like a left handed forehand than a 2hb.
Well it sure is abbreviated. He times it perfectly and guides it almost entirely with his right hand, with the dominant left hand just there for a little stability. Mecir used to do something similar too. Nalbandian too, to an extent although it's a little quicker and more explosive of a swing.I don’t see his backhand being close to a forehand at all. It just looks like an abbreviated backhand.
