My best answer is "dunno".
Maybe for design reasons or they just didn't like it? From a technical standpoint, it does seem like an obvious and sensible way to use all those paper doll textures. They do have some memory overhead, as each individual would need to be composited to a unique texture buffer. Then again, we only see a handful of static NPCs per interior. Surely even a DOS-era game could handle that.
Possibly those paper doll textures didn't look very good at low resolutions? But I just tried it with 320x200 retro rendering and it still looks pretty decent and in-world to me. I only scaled up image here so it didn't look so tiny in the forum post.
