I think the above is quite confusing description. This really is not
about any "shorthands" at all, but just about branches (how the name
implies, after all).

Git and Cogito share the same models of branches. These branches are
'heads' with commit pointers stored in refs/heads/, etc. The branches/
directory says that some branches do not correspond to local development
(and should never be used for that) but instead they correspond to a
particular branch in some remote repository. Such branches are called
"REMOTE BRANCHES".

So it's "if branch X has corresponding .git/branch/X file, it's not a
local branch but instead a REMOTE BRANCH corresponding to the URL stored
in that file". That simple. The URL is address of the repository plus
optionally a '#branchname' if the branch name in the remote repository
should not default to remote HEAD or master.

In addition, Git (not Cogito at this point) supports a completely
different and unrelated abstraction called REMOTES. They don't have
anything to do with branches. Instead, a REMOTE represents a repository
URL and a set of local/remote branch pairs to handle on pulls and
pushes; it has no other obvious mapping to branches and branches can be
even shared between various REMOTES etc. (this is changing lately with
the refs/remotes/ hierarchy, but I think that's still not in wide use).
