Not according to that reference MakeItHappenCaptain posted. A review (no instruction) is simply that, a review. So the person being reviewed is PIC. If things do not go well and instruction is required then the Reviewer can say "My Aircraft" and take over thus becoming PIC.
On a safety point, if you ever fly with another pilot, being a friend, Instructor for an AFR or an Examiner ALWAYS determine before flying EXACTLY who will be Pilot In Command, because if things turn nasty for whatever reason, confusion as to who is flying the aircraft can ultimately lead to disaster.
