Except their apology doesn't do what you're saying as it doesn't say he was innocent or that he didn't violate the CoC. It simply says they didn't fully follow their process and that if he wants to appeal the board will hear it. As I read it he is still considered guilty unless the board accepts the appeal.
edit: And since he seems too emotionally exhausted by this to deal with it further there will possibly be no appeal filed and thus he will stay guilty by default.
