The brushes are at 180 degrees from each other. The alignment has to do with the timing of the brushes and the commutator in relation to the magnets. Electric motors are usually set to have the timing advanced by a few degrees so that the motor can make more power (torque) more efficiently in one particular direction. If a motor were set up to be the same in both directions it would definitely affect the torque curve. Similar to an internal combustion having it's timing before top dead center but obviously not for the reason of burning fuel.

Best of luck!
