This is not accurate. If a user is logged on and a Windows Update requires a reboot, WU will present you with a prompt to "Reboot Now" or "Postpone", and postpone give you the option to postpone from 10 minutes to 4 hours. If you're not there to select an option, it will sit there forever waiting for you to make a choice. I've logged onto Windows 7 virtual machines that had literally been sitting at that prompt for months waiting for someone to click something. And once your postpone limit has expired, you're again presented with the option to Reboot Now or postpone. You could postpone forever if you wanted. The point is, you're given PREDICTABLE options. You're not in a situation where you press a button and you're not really sure what's going to happen, like the TouchPad's "Install Later" choice.

That said, I'm really not sure how the Windows Update restart behavior is relevant to this thread.
