That's correct. Small meta note: I don't like playing "20 questions" 
very much. If you have a theory or want to verify something it's better 
to post your theory and have people comment on it. Posting one question 
to get a yes/no, then posting another one to get a yes/no tires me very 
quickly :-) See also the always appropriate essay from Eric Raymond:
