His point was that documentation shouldn't be taken as the final word since it is not always 100% accurate. Especially when writing kernel drivers. So you do all the dramatic laughing and peeing and ... "THEN, and only then, have you reached the level where you can safely read it and try to use it to actually implement a driver." So you're reading urine soaked documentation at this point. But I guess you're now going to be reading it with the appropriate level of skepticism. A little over the top perhaps, but kind of entertaining.
