SSE Possible dumb question - how do these mods work?

I'm dipping my toes into the Creation Kit and making simple mods, and along the way I've been looking at existing mods I like to try and understand how they function.

 

As an example, Pandorable's NPCs appears to include, as far as content files go, some built-in hair meshes and textures. My understanding is that content files like this can either 1. Be included as loose files which get unpacked into the sub-folders of your game's Data folder, or 2. Be packed together in a big BSA bundle file.

 

In the case of Pandorable's NPCs, I can see the textures for the hair in the mod are unpacked as loose files, but there are no meshes unpacked to go along with them, so I assumed they must be in the mod's BSA file... except as far as I can tell, there is no BSA file installed for Pandorable's NPCs.

 

So if the hair meshes for this mod aren't installed as loose files, and they aren't packed in a BSA, then... where the heck are they? How can this mod work when it doesn't appear to come with the very files it's using?

I've never used or looked closely at this mod but browsing the file contents I'm assuming they added the KS Hairs directly into the FaceGen meshes.
