This is perfectly normal when the DNS server doesn't know the answer
- if you send an iterative (i.e. non-recursive query), the server
must respond with the closest information it has, which may be the
root servers. Also, if the server is configured to not answer
recursive queries from your IP address, it may treat your recursive
query as if it were iterative.

No.

Agreed. That's someone reading a decision tree - make the user go
through the completely mindless steps, because they solve a
significant portion of problems.
Have you tried DNS Expert's analyzer? It will often catch
inconsistent data in the delegation records.
