It's possible to have a module "X" n several module layers at the same time.

It's hard to diagnose things from the info in your mail. Can you print 
the Configuration object for layer A, B and C and paste it into a reply? 
There may be implied readability in the picture, or it may be related to 
using a multi-parent Configuration, I can't tell. Also when you say X 
uses Y then I assume you don't mean services, instead you mean X 
requires Y, is that right?
