Is your service that shall block the subsequent ones in shutdown of Type
"oneshot". I'd expect that the same that is valid for startup is also valid
for shutdown. Quoting systemd.service(5) manpage:

  Type=
    [...]
    Behavior of oneshot is similar to simple; however, it is expected that
    the process has to exit before systemd starts follow-up units.

This implies "blocking behaviour", AFAIU.
