This happens because when we swing our arms (alternately) the motion of the arm about the shoulder ball-socket join produces torque where the entire forearme acts as the leverage.

When we alternate the swing of arm with foot fall (right arm-left leg, froward) the motion in both upper and lower body are opposite as a result the walk is more balanced and unidirectional.
