Looks like he's claiming to have usurped just about every Apostolic See:
His Holiness Bishop Rutherford I Ralphovich of Rome-Ruthenia is the Papa-Catholicos of the Catholicate of Rome-Ruthenia and Supreme Pontiff of the United Roman-Ruthenian Church. He is an accomplished leader, educator, and clergyman with more than a quarter-century of international diplomatic and executive experience. Bishop Rutherford focuses on empowering others to build transformational collaborations while improving the quality of lives. He is 266th in succession from St. Peter the Apostle as Prince of the Romans, 74th Grand Duke of Ruthenia, 142nd in Gallican-Antioch succession from St. Peter, 169th in Greco-Russian succession from St. Andrew the First-Called, 145th in Armenian succession from Saints Thaddeus and Bartholomew, and 116th in Syrian-Antioch succession from St. Thomas the Apostle.
Now, his claim to be the 266th Pope is interesting, as that's Jorge's alleged number. So he must consider Jorge an Antipope?
He wasn't content with being a Cardinal, evidently, so I'm guessing that in light of the Bennyvacantist controversy, he jumped on the bandwagon and usurped the "papacy".
