Same belt, different NSN?

Hello all.

I know that there are US ALICE gear nerds here, but not tagging them directly since I do not know them personaly.

It called my attention that this two belts, which are exactly similar (save the fabric color) have two different NSN's and designations.

Was the non-LC-2 intended for standalone purposes, and the LC-2 marked fielded with the rest of the kit?
