I can't really blame Libby's lawyer for that. Translating from the legalese, Fitzgerald basically ordered him to contact her when it finally dawned on Fitzgerald that Miller was sitting in jail for no solid legal reason, but rather to play the martyr.
I don't believe Fitzgerald has such powers - since when can a prosecutor "order" a citizen to provide a release for someone in jail on a contempt charge? If Fitzgerald really believed that Miller was sitting in jail for 3 months over that - then we really are in a heap of trouble.
