If you change a nameserver name from ns1.vianetworks.nl to ns1.hijacked.cx you
have no parent domain to check authorization against, at least in the c/n/o
Registry.
The authority of non-c/n/o nameservers remains usually their creator.

1. Hijacker registers ns1.vianetworks.nl
2. ViaNetworks registers domain1.com with the nameserver ns1.vianetworks.nl
3. Hijacker renames ns1.vianetworks.nl to ns1.hijacked.cx
4. Hijacker registers ns1.vianetworks.nl

domain1.com would use the nameserver ns1.hijacked.cx, NOT ns1.vianetworks.nl

Did I get anything wrong?

Imho a registry should not allow renaming nameservers with parent domains outside
of their own TLD(s).
