Which ones need to be inverted depends on the number of stages in your gearbox; each stage reverses the rotation direction.

The reason that only one side needs to be inverted is that the motors themselves have opposite orientations. A clockwise shaft rotation (viewed from the motor side) is forward on the left and reverse on the right for no gearbox or a spur gearbox with an even number of stages.
