It's just the way things are done for the shutdown procedure.
As I mentioned above, you shouldn't need to run "restart networking" (in fact, it probably needs to be renamed to something else to avoid confusion), using ifdown and ifup to bring up and down network interfaces directly will do the right thing and avoid stopping dbus.
