No; you're not, as indicated by "Non-authoritative answer". merapi tries
to be helpful and supplies the IP addresses of the nameserver that are
authoritative for ssom.ch, mx0.redwave.net and mx1.redwave.net.

You get the exact same list of nameservers, again non-authoritatively.
Why non-authoritatively? Because the two nameservers you have queried
serve the CH zone not the SSOM.CH zone.

quite what it means. This is not their fault.
