Wont happen so dramatically. By the time anything is melting the aero forces will have far exceeded the probe's ability to point. It will start with a very slow tumble, breaking contact. The spinning and destructive heating will come some minutes (hours?) later. Of course, due to distance, by the time we see the break in contact the probe will be gone, allowing the op's careful language re timings to make it seem like everything will happen at once.
