This is a terrible, terrible video. Putting the wire around the screw clockwise like that causes the electricity to flow the wrong direction. Remember a classic saying my RV teacher once told me, “wire on ‘left’ is a move most deft, but a wire done ‘right’ is actually wrong.” This handy mnemonic is called the “woliammd,” all electricians are taught this in first year electric school.
