Your nitpick is warrantless - it should have been obvious from context
that I was speaking of the general purpose of these name servers from
our perspective - not implying they were somehow authoritative for
recursive queries. If it makes you feel better I'll call them my
"pedantic" and "irrelevant" servers rather than my "master" and "slave".

A nitpick here: the terms "master" and "slave" only apply in regards
to authoritative name service. When you are doing recursion, this
distinction is irrelevant.
And no, this is not odd at all. This is typical for many or most busy
domains: they do a rudimentary form of load balancing through DNS
results. Nothing interesting here.
