I've never had a conversation with him about his sedevacantism (the belief that the office of the pope is currently vacant...meaning the current pope and however many previous popes aren't legitimate), so I'm not really sure. But the conceit of the sedevacantist is that they are better equipped at understanding and navigating the truth of God better than the magisterium (teaching authority) of the Church. I do hope he does repent and come back into communion with the Church.
