You're description of how the name would be looked up is essentially
right, but only the very last query would give you an authoritative
answer. The others would all result in a referral to the nameservers 
for the next domain down towards the information you're looking for.

In the Additional Section of the response. The required A record, often
called 'glue', will be included. However some registries, including
ours, will only announce glue if it is required for the delegation to
work. This means you won't necessarily get glue for every nameserver in
the referral.

If you still think the Swiss NIC are DoS'ing you I'd go for "out of your
mind" :-)
