--emptytree has nothing to do with rebooting. It simply forces emerge to
rebuild everything in @world and their dependencies. Once you have done
that, you will have daemons still running the old code, which you could
fix with a reboot, or you could run checkrestart and restart only the
affected programs.

After an emerge -e @world, a reboot is probably best, another reason to
avoid the unnecessary step of emerge -e @world in the first place.
