The second doctor should be able to make a second diagnosis without having to ask a new doctor to do so.

The first opinion is the one that the doctor gave the first time, so it's important that the second doctor have the same opinion as the first. So, for example, a doctor who has given the wrong opinion to a patient might have to ask for another opinion from another doctor. This would be like asking a new dentist to give a new opinion on a patient who has had a heart attack. The doctor would then have to explain why the patient had the heart attack and why they didn't know what it was.
