I think he's actively lying with this to have some amount of plausible deniability.

If you look at pseudoscience "alternative health" treatments on YouTube, they always have some disclaimer saying "This is not medical advice, I am not a physician, please consult your doctor", and then immediately go on to tell you about how injecting yourself with ozone or drinking paint thinner will cure all your diseases. I think it's just a legal disclaimer, not like they are actually aware that what they're doing is bullshit.
