Will the geographic restriction be lifted if the non-primary parent moves out first?

We are working on our final decree of divorce. My husband (non-primary) wants me to remove the paragraph about lifting the geographic restriction after he moves out of the restriction area. He insists to limit me to stay in the same county for the rest of 17 years even if he moves out. He said from what his understanding, as long as he follows the visitation schedule, the court will not lift the geographic restriction for me to move out even if he moves out first. Is that true? Is it better to keep the lifting geographic restriction paragraph in the final decree or is it okay without it? I want to be able to move out after he moves.
