I don't believe Braga is an Ex-producer (as many as there are), Manny is. In 24 Manny is the senior writer and is higher up the ladder than Braga which is the reverse from Enterprise when Coto was under Braga, then Braga left before season 4 and Coto moved up.
Braga is listed as "Co-Executive Producer". I think it was Ron Moore who explained this - "Co-" means "you're not".
Interesting that Sutherland himself has been bumped up to Executive Producer.
