Well to take the second point first, I can't imagine why ATC would ask whether you were changing to CTAF. Nevertheless, in relation to the first point, if you're monitoring both frequencies continuously all I need to know is that you're still listening to me. And if you haven't told me you're changing to CTAF then I assume you are.

ATC has no way of knowing and really doesn't care, so long as we know when you're listening to us and when you're not.
