I think we're focusing on different aspects of this image. You're talking mostly about the shadow. I'm talking about two different sources of light in the image.

The light that is producing the upper band (labelled "1") is being reflected back (you might prefer scattered back?) whereas within the mountain's shadow, where there is not so much reflected light, one can see the Moon (labelled "2"), whose light is coming to us from beyond our atmosphere, straight through the atmosphere to us.
(By the way, I assume the light hitting the Moon from the Sun did not first go through Earth's atmosphere on the way to the Moon, except for some exceedingly tiny fraction of it.)
