I'm not sure how much this helps, but...

If the only answers they offer are yes or no, it's a very tricky question to answer with anything other than traditional instruments. I have an electric piano and a synthesiser and they both use samples from a third party. All GM synthesisers will be the same. BiaB is the same. Kontakt instruments are the same, etc.

I imagine that a simple Yes answer, which is honest and accurate, will likely cause them to reject your submission. It's possible that answering No will simple mean you'll get further questions about attribution/copyright, though I suspect it won't.

If they're to police fully, then they really need that declaration of attribution/copyright, but I suspect that either they feel that leaves them too exposed, or they haven't thought it through properly.

If it were me, I'd be a little mischievous and ask them it it applies to samples inherent within an instrument like an electric piano. I personally would count BiaB as qualifying within that. If they say it does, then I cannot see how I could submit anything I produced to them.

Otherwise the only 'proper' option, IMHO, is to go elsewhere :-(
