It is my understanding that the instructor that discussed detailed answer info with you was acting outside his privileges (he should not even have access to the answers unless he is also a ground examiner or flight examiner). If he is an examiner his instructions are quite specific - whether the student has passed or failed he must not discuss questions or reveal answers in anyway. He is only allowed to advise general areas that require revision. There are bona fide reasons for this policy.
