Wow. I looked into what you are mentioning. Just wow...

I see a host demanding a guest reduce their answer which might require many words down to either "yes" or "no". Clearly the guest's answer was not as simple as "yes" or "no" but the host required the answer be that simple. They clearly weren't pressed for time so I don't understand why the answer had to be only one word. Maybe the audience doesn't want to hear more than a one-word answer?

Yes I can see that, but do you think he would be telling his life story if he could substantiate his claims? I think not.
