Sorry, you were right, that's what it means.

gonai A gi B = (not A) iff (B)

It's equivalent to: not (A iff B)

I'm not sure I see how. But you could do it like this:

        ta vasru lo tcati onai lo ckafi i xu go'i lo tcati
        That contains either tea xor cofee. Is it tea?

I can't think of a simple question in Lojban that both asserts that
it does contain one of the two and simultaneously asks which one.
