It's a very specific type of lighting that this is to combat, hard shadows on real time lights with no directional light otherwise specifically.
Plus the value I'm using as a minimum light is very small, 0.005 (I usually use 0.002 on models, upped it a bit more to give a better example) in this image on the left cube vs 0 on the right. Not enough to make me glow like the sun in darkness, but just enough to give the color of the texture the chance to bleed through the shadow.

And you might say I'm being picky, but heck it's my own shader so I'll be picky.
