Yes, this is correct. Steve's code by default does only one
sessionsetupX call which gives only one vuid (virtual uid).
All accesses to that share will be done as that user.

Not "in future" - currently and by design. Remember, we don't
allow arbitrary uid changes on a CIFS connection - we only
allow chown when a user is mapped to root on the server
