The purpose or intent of the bill in this set of clauses is obviously to give some guidance to what might be sentencing provisions. In this particular instance it essentially says that the offender may not apply until the period the court considers appropriate. There is the potential circumstance of what one might call “habitual offenders” and there might be circumstances in which the court may wish to recognize that there is a regular or systemic issue, as opposed to simply meeting the conditions and releasing one's conditions.
