Strictly conjecture, but the Squarish transition of the oil cooler to the cooling airduct is present, as is a good deal of the other ductwork, and rather than at first seeing a squashed nozzle, I think it looks rather circular. On the whole less obliterated than I would imagine (first structure on scene of impact) would present. The APU is fairly lonely and absent a lot of structure that is present in other areas of the tail, so its relative good look is a surprise to me.....perhaps it lost connection to the tail cone immediately. lomapaseo or Turbine D would know better, but does this power unit's condition suggest it was not running at impact??
edit to add for deSitter: By no means am I attempting to minimize the impact forces, elsewhere I refer to "it appears nothing remains attached to anything...."
