The same branch even?  Why would you want to do that?  Are you
trying to increase speed?

In general, concurrency on an OSTree repo is not yet strongly defined;
however, you can rely on commits and pulls of different branches being
safe.

The hashes in refs/heads are not necessarily unique - it's quite
possible to have the same repository content (i.e. commit objects)
in multiple locations. That happens very often with git.

The data in objects/ though is unique - it's a content addressed
store.
