Answering without thinking much, I don't think the cutaway_textures
feature copies the inside texture(*), but maybe I'm not remembering
correctly.
A reminder the yuqk fork fixed a cutaway_textures bug which exists in
official POV-Ray releases. See:

(*) - The inside_texture{}s feature has a few inconsistencies, besides,
with respect to how texture{}s are handled.
