What you can do if you're uncertain -- and my language was sloppy, good point! -- is say "hey, I'm not sure what you meant here; can you clarify?" And I say "yeah, I was unclear. I meant that the question was related to treaty status but after digging in, it's not required by treaty for that elected position to only be occupied by someone of a specific heritage. Thank you for pointing that out."
(I might not have said thank you, to be honest, and of course you're welcome to assume I'm just covering up because you called me on the phrasing.)
