Yes

I just checked the internal overlays team guide[1] and it does 
explicitly say that repo_name should match the repositories.xml <name>. 
So probably there is no problem. That being said it is possible for the 
owner to change repo_name and (accidentally) not update 
repositories.xml. These cases should be fixed but exactly how would have 
to be determined on a case by case basis.

In any case, this is just something to keep in mind when writing this 
check. It is not fully guaranteed that eselect repository can find the 
repository that is requested in some master= entry.
