Seems you skimmed rather than read those four pages. The problem, as repeated a few times in this thread, is when the game design doesn't support turning off the quest compass. (Even if there is an actual option for it, which yes, there usually is.)
You should've kept watching. Later in the video he brings up another quest in The Witcher 3 that doesn't give you any directions, and he also highlights the fact that there are no printed names on the map, no road signs to read, or any other means to navigate, except for, well, using the quest compass and/or the dotted line.
It's fine if you don't think of it as a problem, but please don't dismiss the arguments after ignoring half of what's being said.
