Its f.quit_mwm function exits the mwm program, but that does not have any effect on the X session - the session continues without a window manager (which is possible). Only if the X process is "connected" to the window manager process using "exec", it will exit, and so quit the X session entirely. This is what "init" or "startx" help to do: They source the .xinitrc file and execute it. Its last line, the "exec" statement, creates the "connection" between the X session and the program which has control over its life, usually the window manager - but it could also be an xterm, and when _that_ xterm is closed, the X session terminates. The line "exec /usr/local/bin/mwm" will do this.
