0 = shadow on side away from sun (no atmosphere to scatter light into a shadow)

1 = sunny side slope with various angles and surfaces reflecting light up to a 1 but at any rate very bright compared to the shadow side

They are SHADOWS on the side away from the sun and light reflecting off the opposite side of the elevation/small peak that is casting the shadow.

And the sunlight is coming in at a fairly low angle. The same spot with the sunlight coming down almost vertically would be pretty featureless as seen from the Earth while if the sunlight was at a bit lower angle the shadow could be longer and the reflecting side would appear differently also.

Where did you learn your definition of "albedo"? It isn't a thing, it is a measurement of the % of light reflected.

Here is the short definition from Wikipedia (the first entry I found that I could copy and paste):

Albedo is the measure of the diffuse reflection of solar radiation out of the total solar radiation and measured on a scale from 0, corresponding to a black body that absorbs all incident radiation, to 1, corresponding to a body that reflects all incident radiation. Wikipedia

So you don't see "albedo" the moon has "albedo" and it varies depending on the color, texture and surface angle in relation to the incoming sunlight from place to place.
So you have an elevated feature on the moon and the side away from the Sun has a deep black, sharp edged shadow with essentially '0' albedo and the side of the feature facing the sun you get various degrees of high albedo up to nearly a 1.

Those are shadows of pointed elevated features. If you get a good sharp image of a full moon through a telescope (stitched multiple images to make a complete photo of the moon on a decent scale and search you will find many shadows like this of various shapes and sizes.

Rubbish eh? Well that goes both ways. Since you can not disagree as a gentleman, I'd say your brain is rotten for not seeing something clear as day. You can not even read a map scale right. The 2 triangular shadows you are looking at is about 120 & 160 meters long. That's 393 & 525 feet long.
If your really working there in NASA, talk to guys who knows what is going on and get the right facts straight out the horses mouth. Your parabolic antenna is a crater. Just look at the edges, it is rough & wavy. Its not smooth as a precision device should be.
