Check your link.... I'm not sure but I think the link is generic and is pointing to the most recent video on your shared list. If the viewer has a YouTube account they will see that same reference from their shared list. I'm getting a video from my own shared list when I click on the link. I can do a reply with a quote to see your link, then cut and paste it and it works okay, but clicking it from your post gives me one of my own videos. I'm really not sure how this is happening and I used to do this for a living!
