Tom, my personal guess is that it had already developed those thumbprints
before it became oriented. Its rapid plunge through the Earth's atmosphere
allowed it to develop a roll-over rim but there was no time left for the ablated
material to "envelop" or "inundate" the rear part which is usually warty or/and
shows ripples.
