I just tested it now, and yes it does.
But it does not make it any better.
It is absolutely confusing and meaningless to see the same name three times in a row, and everyone in our team thinks it is a bug.
If you want to make three links to the three posts that are all assigned to the same user, then make each clickable item in the list visually distinct. For example, mention the user name once only, and then list post numbers, each clickable (e.g. #2,#23,#51). Alternatively, say “Slava (3)”, and have up/down arrows to the right of it, that will move you to the previous/next message assigned to Slave as you click on them.
The way it is presented now, it makes no sense whatsoever, and is counterintutive. It just looks like a bug.
Moreover, if your goal is to show all of them at the top, then also highlight the one that I just clicked and navigated to. What if there are 5, and I just clicked on the second one, then I read it, and now I want to click on the next one. But by the time I finished reading, I forgot which one I clicked, was it second? Which one should I click next - is it third? It is impractical the way it is implemented now.
