They simply mounted a digital video camera with the main camera and captured the identical shot on both cameras.

Then they'd have a "group chimp".
That isn't entirely correct. Motion picture film has so much latitude that we would never use the assist to make any decision regarding exposure or lighting and would roundly berate anybody that did. Assist pretty much exists so directors can second guess what they saw the first time around. As a director of photography/cinematographer I never looked at it. The dailies were where the rubber met the road.
