It doesn't use a repository. It uses a dedicated cache directory. 
Usually it will use the same file with hardlinks to the usercache and 
repositories.

The implementation is not a one-liner but quite readable: 
http://selenic.com/hg/file/894a5897a9dd/hgext/largefiles/lfutil.py#l52

It really should be documented and exposed, similar to how 'hg help 
config' explains configuration file locations and how 'hg showconfig 
--debug x' will show which paths actually is used.
