Use a fixed-racket image for clubface control
The instructor recounts a tennis lesson where rolling the racket for topspin cost power and control; fixing the racket face down and brushing up the back of the ball created more structure. He transfers that image to golf by asking the golfer to keep the clubface fairly fixed throughout the swing and feel the structure instead of rolling the face.
