No, surely it is an ordinary join.  At the far UA, there are two incoming dialogs, each with one audio m= line.  The only oddity is that one dialog is recvonly (at the far UA), and so is never sent media.  The other dialog is sendonly (at the far UA) and so never provides audio to the mixing, but is only sent the result of the mixing.  The effect is that the far UA's input audio is sent only to the second dialog, and the far UA's output audio is driven only by the first dialog.
