Question about friends list sorting.

So now that we can sort players on our friends list. Does that mean they fixed the friends list bug? The bug I'm talking about is the one where if I were to add you to my friends list and you accept my friends request. And we become friends but later down the road were not friends anymore and you decide to delete me. But it will still say were still friends on my friends list. And it does not remove you from my list. So have they fixed it where once someone deletes me from there friends list it also deletes them from mine as well?
