ANY gap insurance only covers that amount of shortfall between the insurance settlement, and the amount still owed on the car/early termination cost. It primarily protects the lender; the owner/lessee is only covered in that he/she will not have to come up with the difference. But that person is not going to get their down payment refunded either.
To answer the earlier question, yes the statement quoted by Planet4Ever from the NMAC lease contract sounds just like gap insurance.
