That's because you asked the wrong questions.

What you want is to query for the NS records, which give the desired

There is no way that query would get you what you're looking for. All
it will produce is a referral, which is what you got. You could
however substitute NS for SOA in this query too, and you'd once again
get the right answer.
If you're never wrong, you're not trying hard enough
