Actually the sensor does provide you with rotation direction information, but it is not easy, nor worth while to obtain IMO. You would need to measure the length of the pulse width of the signal. In the sensors datasheet it does say what the lengths of the pulse widths are. They are different for forward moving(CW) and reverse moving(CCW).
