A lot of artist labels are really just subsidiaries of larger record labels. While some of them might have some room to negotiate for differences from the standard contracts present by the parent company at the end of the day they are not going to allow a subsidiary to deviate too far from the parent's interests and policies.
In this particular case I'm not sure whether or not Trent or any of his immediate people actually signed off on (or were aware) of the RIAA's action. It's highly likely that there's a clause in his contract that allows the parent company to take action on their own and the present situation probably arises from the legal departments and marketting departments not communicating promptly or adequately.
