That is not the term that is used where I practice. However, it may mean that the county attorney wants to make a recommendation at sentencing which may include additional jail time rather than discharging him from jail with credit for time served.
Open ended or "open recommendations" simply means the prosecutor is free to argue any lawful sentence. Te prosecutor will likely use all the facts...even those underlying the original theft 3 charge, at sentencing.
Your lawyer should be able to explain this in greater detail.
