No, this was never implemented really, it was a bit tricky at the time because Twitter 'replies' also show up publicly in the public feed, and the problem is that friends only lets messages show up in one single 'feed', so if we marked replies as replies, then they wouldn't show up in the main feed at all. So basically this is a matter of a poor mapping between friends' model and twitter's messages.
