This is how I am reading it as an wheel analogy; 1. Maintaining vacuum state costs energy. 2. Using energy you can change wheel rotation from clock wise to counter clockwise. 3. By using energy when changing wheel ration, wheel rotation energy is not effected. I am almost sure it is false thought :)
