Well, Seren said that in a private conversation when I asked them how skin actually works, can't exactly give you a link, but I'll post a quote.
As for ARMA, check out creationkit wiki. I don't exactly understand why they even need to use the skin swap in the first place, nor do I understand how it works.
Those skin swap are mostly used with special models specifically made for Khajiit and Argonian, mostly gauntlets. There are no Khajiiti or Argonian specific models for armors like Hide Armor or Fur Armor (which shows a fair amount of skin on male and female), but they work just fine.
If you want to apply different texture at runtime, I don't think it's possible with vanilla script functions. Even color variations for Monk Robes are done via TextureSets, which are applied to correct nodes (most vanilla meshes only have 1 or 2 nodes), and they use entirely new ARMA and ARMO. Not to mention that custom meshes tend to have different nodes for the skin/armor part. Closed vanilla armors (like robes) do not have skin node at all.
IIRC SKSE has functions for dealing with TextureSet, but yeah, see above about nodes.
Mostly, skin texture is dealt entirely by the game engine.
