Those settings *are not* supposed to close an idle ssh session. Nothing
in ssh is supposed to close an idle session. There isn't any facility
to do that, because it's entirely contrary to the design of ssh.
Your TMOUT solution is the standard way to appease the managerial morons
who are asking this of you. It asks the shell to terminate if it's
sitting idle for however many seconds you specify. If the shell closes,
then the ssh session is free to close as well, assuming there are no
active tunneling connections, etc.
