Why were "last light" and "first light" on the same side of the moon?

Given that the moon passed through earth's shadow in tonight's lunar eclipse, why were the last light before totality and the first light afterwards both on the right side of the moon? I don't think solar eclipses work that way.

    Look at the diagram on this page: http://sunearth.gsfc.nasa.gov/eclipse/LEmono/TLE20...

    The Moon passed close to the SW edge of Earth's shadow in this eclipse, so that edge of the Moon got last and first light. You might have noticed though that the last bit of light was towards the top, while the light returned towards the bottom.

    Also, because of the shadow's off-center path, the SW edge of the Moon did not get as dark as the rest of it.
