It is possible to click on this question title above ↑, which would cause the page to refresh.
I'm wondering why the question title is a link to itself and the same page? Why isn't it just written as solid text? SEO perhaps?
I personally use this link quite often to refresh the question or to copy the link to the question. I find it quite useful.
I believe that is because you can access a given question in different ways, and you might want to share the link of the question itself. Giving you a canonical link somewhere is good design and polite to your users so they don't have to go through hoops to get it (go to address bar, delete everything after the number, etc).
I presume you are referring to the circled title. Well, why wouldn't it link right back to the page? I would presume that it is a forced refresh (not from cache) for the question.
I do use the link to refresh when I am watching for an answer. Seems to be
a better refresh than equivalent to using Ctrl-F5.
For me it has several benefits:
Remove the anchor to a comment or answer if I want to refresh the page
For example: Open a comment link (like this one). The page opens and scrolls down to the comment. When you now refresh the page it keeps going back to the comment. If you want to go to the question instead if you refresh, click the link. The comment anchor will be removed from the URL and the page won't scroll down any more.
