Unfortunately, it means you haven't been accepted yet, and that means, until you have an acceptance, that you have to plan as though you won't have one.
It's not great since, as you can see, they have been sending out As all along. The good news is that these guys have a very high II-->A conversion rate, so it really isn't over with them until it's over.
There is nothing to do except periodically sending updates and letters of interest/intent (enough to be persistent and make your interest clear without crossing the line into annoying them or seeming unreasonably desperate) and waiting. If you look at prior year threads, they do send As out right up until the end of their cycle, and people with early IIs have historically been among those receiving late As. It's not a guarantee though, which is why you can't count on it. Good luck.
