I see that this is not happening, at least if starman receives the --user and --group parameters.
I have use --user teddy --group teddy in the upstart config, and even though I execute "start prg" and "stop prg" from the root account, all the starman processes are owned by teddy account. And there are 11 processes, even though I asked starman to run 10 children, so the master process is also owned by teddy account.

I've seen that not all the processes started automaticly use upstart under Ubuntu.
For example, I can manage apache2 process using
service apache2 status
because apache2 uses a SystemV script.
I read somewhere that upstart can work somehow with upstart scripts, but that the old SysV init scripts are also executed... but I don't know if it can also work in the same way with SysD scripts...
