You agree that "if A selects B and B depends on C, no dependency of A on C is 
deduced", right?

The implication is that the user can enable A, which selects B, while C is 
still disabled. The B -> C dependency is violated, and the build will fail or 
bad things will happen.

I hope things are now clearer, even without the description of the testcase 
where this happened.
Inform me of my mistakes, so I can add them to my list!
