Here's another article by Anastasia where he also calls Joey the "former" mob boss. He always calls him that. However, one of the sources he used for that article, says otherwise:
“It was a stupid thing to do,” said another underworld source while discussing the meeting.
See what I mean? It can go both ways. There is nothing "to taste" until Joey does his press release to announce that he is or isn't the boss of Philly.
