I think its just doing a simple pass looking for ghosting and substituting the information from a single frame much like HDR software does. It doesn't seem perfect, but it is impressive that it even works at all to be honest. You can easily extract a single frame and use that to correct any left over errors in Photoshop too. Nifty.
