Have a look at the two attached screenshots. In the first picture you are warned about a necessary log-off & -in, but the menu on the second screenshot gave you only "Restart computer" option.
I guess the hint from a recently installed security update was to restart the machine, so the "You will need to log off and log back on" is perhaps misleading. Or provide the "Log off" option in the menu, in case the hint was "After installing the pkg ask for 'Log off'".

bugfix: when the restart mode is session then offer logout, rather than restart. Fixes RH#475781
