If you share internet wifi you will get similar recommendations based on what others on the network have watched...not just based on "your" suggestions. Could be that. Metaphorically...Both of you were offered "the same meal at the cafeteria" so to speak. Based on what "others" who visited that particular cafeteria had eaten in the past. This happens all the time to me when I visit friends. I realize the reason I have a suggestion on my youtube was because that was what the person who I was just visiting would want to watch. Linkedin does this too with suggested contacts. I would imagine spotify and others do as well. I said one day to a friend of mine how it was "getting creepy" and his response was "Isn't this what we have been asking for though?"
