Typically I am the first to pile on systemd - but this one is silly. There is absolutely no guarantee that dns resolvers will be queried in order. The implementations of this vary drastically - some implementations make the request to all dns resolvers configured and simply use the response that comes back the fastest. The implemented a hack that seemed to "work" but made poor assumptions as to why. This is not the correct way to implement split horizon DNS.
