That requirement is described briefly in the smf_method man page:

     The required behavior of a start method is to delay  exiting
     until the service instance is ready to answer requests or is
     otherwise functional.

If your method script starts a server process in the background and
then immediately exits, it is broken.  In most cases, the start method
should make sure the server is accepting connections, or otherwise
fully operational, before it exits.  Likewise, the stop method should
ensure that the server process is fully shut down before it exits.
