AFAIK there isn't a hard and fast rule. You need to look at what yum has
updated. Thus if it changed the kernel or libc, you should reboot
whenever convenient. If it changed an X driver or the X server, or the
basic part of your desktop manager, you'll want to logout and in again,
usually restarting X in the process. If it changed a running
application, quit the app and restart it, etc. etc.

I agree it would be nice for yum to tell you this explicitly.
