In principle, yes - if a new “ServerMediaSubsession” object happened to be added to the “ServerMediaSession” sometime after the “SETUP” command was handled.  (Normally that won’t happen though, because normally all of the “ServerMediaSubsession” objects are added to the “ServerMediaSession” before the server starts handling commands.)
