Is it, though? I'm still unclear who exactly would be likely to see your reply, but upon clicking on it would not be able to see the original. I don't find that happening to me?

That is, I don't come across replies for which I can't easily see what they are replying to.

Perhaps more likely people who can't see the whole thread won't see your (or any other specific) reply at all? Obviously I'm still somewhere speculating here. :)
