It appears to be a lower friction alternative to an already low-friction friction saver. It clearly is designed to be used as part of an access line component using a traditional 2:1 ascent/descent system. Advantages? It swivels.

Revolutionary components to make an already difficult system more complicated. Anything to try to make the 2:1 system easier, but the physics of the 2:1, and gravity, trump all efforts at making some part of the system easier. No matter how much gear you throw at this system, it is still just what it is.

I normally embrace new gear, but you can't use duct tape to fix the hole in the side of a ship.
