Yes it will be combined with your original contract and use year (when that occurs, you have an original contract number and then the new one will be the same number with .1 added at the end). If resale, you need to make sure that Disney is aware that you want it combined before closing. Note, however, that the points retain their identity for reservation purposes, e.g., only AKV points can be used 11 months out at AKV, only BLT points at BLT, and thus you cannot mix them together at 11 months out to book one resort.
