I think Scarborough's first name is Amanda, but I am too lazy to look it up. He is reinforcing good mechanics where as the excellent example posted by BoardMember below shows a pitcher pulling out her shoulder, to pull her backside, or pitching arm through. They sensation is one of adding power, but it affects the arm "circle" and power-line in a negative manner. If you think of it, many coaches try to teach their pitchers about directing all energies in the pitching motion directly at the target or catcher's mitt: stride, arms at pushoff, front hip, rear hip into front hip, back leg, arm swing, and.....that flying glove arm. This energy in BoardMember's video is redirected, which pulls that force off the power-line. To keep 1/2 the ball off the white of the plate, you have a "window" of less than 6" in softball, and 4.5" in baseball for it to be a strike.
