Get the trail arm in to set and load the club
The coach contrasts two positions for the trail arm and their effect on how the club loads. He says that if the arm works away from the body and then hinges the club, the club is not loaded up enough and it causes extra arm swing; if the arm is in the right position, the club sets and loads better with no additional hinge.
