Gear ratios used to be specified one stage at a time. This was intended to allow for the ability to dynamically determine whether or not to invert motors. However, not every type of reduction stage inverts the direction of motion. For example, a gear reduction changes the direction of motion while a belt and pulley reduction does not.
