The documentation states  "In a typical setup with a central Mercurial server, the user who serves the central repositories will get a user cache that acts as a central store for all the repositories. This central largefiles store has every past revision of every largefile". That's what I want, but how does largefiles know which repository is the central repository?

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:

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.
