I think this behavior is probably driven by people like me, who use youtube mostly for music. I repeatedly listen to/watch performances on youtube because to me it's the only streaming service I have. I frequently come to youtube just to watch stuff I've already seen. I find the recommendation in that context to be uncannily good and they keep me coming back to find new music and to see the cool performances I've already seen. Maybe youtube has trouble differentiating these use cases?
