That only proves that limits are written into SOME appointments or elected positions. I deal with terms daily in contracts. The language is the same. It's no different than a contract that has a term of 2 years. At the end of that period the governor can decide if they get reappointment for an additional 6 years or not. Email any attorney and he will tell you the same. You can't read into this and place term limits. The language is not there to confirm or deny term limits, thus it is allowed.
