Most libraries aren't so central to everything that runs in Linux, and restarting the programs that use the library in question is a perfectly fine way to ensure you get the new library loaded. But libc is so very central to absolutely *everything* (or nearly so) in Linux that the best way to ensure everything gets the new, patched versions is simply to reboot.
It is true, but still reboot should not be so essential for glibc upgrade. You can just restart (not reload, SIGHUP will not help) services on your server and they will load new glibc. This will allow yout to delay server reboot until next kernel upgrade.
IOW server reboot is easier but is not necessary.
