service dependency between graphical.target and multi-user.target

[root@mainlaptop ~]# systemctl list-dependencies graphical.target
graphical.target
├─network.service
├─rhnsd.service
└─multi-user.target
  ├─network.service
  ├─rhnsd.service

The above output is trimmed for brevity

graphical.target is dependant on multi-user.target but i see couple of services which exist on both graphical.target and multi-user.target (network.service and rhnsd.service). My doubt is won't it be sufficient to run both services in multi-user.target. What is the need to run both of them in graphical.target too.
