In this case with the overlapping bit of the torus I think it just merges 
the two possible pigments onto the interior surface.
I tried an image map and a brick pattern with your code and both worked, 
after a fashion, but were obviously quite distorted as I think one would 
expect. Would I be right in thinking that your image file 
"texture_bowels_test.png" is quite a random sort of texture? If so you may 
be able to 'see' the distortion easier with a more regular image or pattern.

In any case it may be easier to get what you seek using a simple cylindrical 
or spherical warp.
Indeed, if it's an image map then just using map_type 2 or 1 should deliver 
a result with far less distortion.
