How would it be subordinate?
A full clone is just that: a deep copy, with no dependency implied.  You can 
push and pull entirely independently.  It’s the same as downloading another 
copy.

Indeed, that’s what I would call “distinct”.

If you are looking for a distinct working directory, but not a distinct 
repository, “git new-workdir” is what you want.   The actual repository is 
locally shared, but you can have a second (and third) working directory, which 
typically will hold another branch.

It’s not what I would call “distinct repository”, but it’s a distinct directory 
hard-linked against the original repository.
