I got the impression that he didn't become a 'team' member until recently. When we saw him with the Blowfish and the lesbians he was certainly working under duress. He could have continued to work as a kind of mercenary or special operative for the rest of the Century, yet still take time out to fight in the War or any number of other events that the writers may care to invent in the future.
