He replied to that personally, let me try to repeat his argument (I cant find a link). He argued that giving advice to other people is completly accepted if the advice doesn't come from a mental health professional. (You'll find plenty youtube videos on how to "overcome procrastination") However having the better understanding of the mind that a professional has can't lead to worse advice, so he too should be accepted giving it. Whether there is an inherent danger of talking to an psychiatrist in this interview format for the interviewee I don't know, but given the amount of disclaimers he's putting out there it seems save to me.
