It is no surprise. The Moderator of the Common Cause Partnership, made up at this point of bishops mostly not recognized as part of the Anglican Communion or deposed by a church in the Anglican Communion, was clear that if invited "back" he would become the bishop of those clergy and laity that became part of the Province of the Southern Cone. He insists, however, that this is the Diocese of Pittsburgh and that he has taken the Diocese into the Southern Cone for a temporary period prior to the development of a new improved Anglican Province in North America.
The Moderator has been deposed and is no longer a bishop in the Episcopal Church. So it seems oddly unnecessary to say that he cannot therefore be the Episcopal Bishop of anything. He may, as a bishop in the Province of the Southern Cone, exercise a ministry in the United States and in the Pittsburgh area. In doing so he stands in violation of long standing ecclesiastical authority that would consider him an intruder and usurper. There is nothing much to be done about his saying he is the Bishop of the Episcopal Diocese of Pittsburgh except to say that he is not speaking the truth.
