The retcons have been going on since the first sequel. Master Miller is a very asian looking man in MG2, and he's described only as Foxhound's drill seargant. Holy shit his role gets progressively bigger with each games, until he's Big Boss' litera right hand man.

To make Liquid's impersonation work, Miller's whole design is turned into a Liquid clone and his full name is given as McDonell Benedict Miller in Metal Gear Solid. Then LATER he's given the full name Kazuhira Miller with ZERO explanation why he's given two completely different names.

Simply put, these might as well be separate characters at this point.
