Just while we are aside :)
Yes, that's better programming practice in general.
However, in this case the script will be killed anyway, when the server 
crashes.
(Assuming it's run as intended from within the session, of course)

And if the user during his session temporarily stops the
screensaver for later to resume it, the script will keep on going.
With your version, the script stops when the screensaver stops.
