It's a combination of that and focusing on recommending videos in depth on whatever topic it thinks you're most interested in. I don't want to watch fifty videos about swords. Three is plenty for now. I want to watch a bunch of different videos and shallowly explore a lot of topics, and the YT recommendation system is extraordinarily incompetent at facilitating this exploration mode.
