Haven't given it much thought, but my first reaction is: the phase only tells you the angular position of the moon relative to an earth-sun line. The upper/lower limb question would depend on whether the moon is above or below the ecliptic, or am I mistaken in thinking the moon's orbit is inclined slightly from the ecliptic?
