The "no automatical reboot" GPO setting is a little misleading in that it does
not prevent a reboot but rather postpones it if somebody is logged in. I
believe the recommendation is to manually apply patches to critical servers
during maintenance periods (put them in a separate OU without different GPO).

"""
No Auto-restart for Scheduled Automatic Update Installation Options
This policy specifies that to complete a scheduled installation, Automatic
Updates will wait for the computer to be restarted by any user who is logged
on, instead of causing the computer to restart automatically.
If the status is set to Enabled, Automatic Updates will not restart a computer
automatically during a scheduled installation if a user is logged on to the
computer. Instead, Automatic Updates will notify the user to restart the
computer in order to complete the installation.

Subject: WSUS overriding GPO for reboot
Hello,
I'll put this here because I regard a spontaneous reboot of a live server as a
security issue (Kind of a DOS):
I approved some bugfixes for Server 2003 in WSUS.
In the GPO which applies to the Servers I set "no automatical reboot", no other
GPO overrides this.
Now all XP and 2000 Clients got a "Computer is going to restart now [OK]"
messagebox while the servers simply restarted without any warning.

Does anybody have an explanation or can point me anywhere where I can find one?
MS KB didn't help me yet.
