Ah, I missed the "target units" part, but even then
"Requires=network.target + After=network.target" is a common
enough pattern for services that need network to be up at startup and
After= line is present in each one of them:

  /lib/systemd/system/noip.service:Requires=network.target
  /lib/systemd/system/dnscache.service:Requires=network.target
  /lib/systemd/system/tinydns.service:Requires=network.target
  /lib/systemd/system/remote-fs.target:Requires=network.target
  /lib/systemd/system/ziproxy.service:Requires=network.target
  /lib/systemd/system/ejabberd.service:Requires=network.target
  /lib/systemd/system/dhcpd.service:Requires=network.target
  ...
