Actually, I discussed that with Michael Stapelberg when we worked on the
dh-systemd helper. The problem is, update-rc.d doesn't provide any API
to query if a SysV init script is enabled or not. We filed a bug for
that a while ago without any feedback so far from the sysvinit
maintainers [0].
So, when adding a native service file, it's not really possible to
mirror the enabled state in a way which works universally and I don't
think there is anything we can do in the dh_systemd helper regarding
that. I'm also not sure if it is fixable manually.
If you add the code into postinst before the #DEBHELPER# stanza, the
service is not setup yet. If you add it after the #DEBHELPER# stanza,
the service has already been started.
