It is best to assume that if you re-apply that they will pull out your old application and see what has changed. If you do not get in and decide to present a different career objective, then do not worry. People change careers objectives all the time -- and this is especially true in the earlier phases of your career where you exposed to so many different industries and functions for the first time.
The one thing that I would warn about would be submitting a mediocre application for the 2+2 program -- nothing can be more damaging now than submitting something that does not best reflect your abilities or potential (again, just in case they do decide to reference it upon your re-application).
Good luck.
