I suggest people give up trying to work out how it hit the water based only on the wreckage pattern.
Take a look at the vids for the Ethiopian Airlines Flight 961 water "landing". Bits ended up scattered every which way. Now imagine they don't all sink at once and they have thousands of feet to descend. Unless you knew what happened I very much doubt you could work out how it impacted the water from just the wreckage pattern on the sea bed.
Likewise the Titanic. The main part of the ship ended up facing north but not many people think it was steaming due north when it sank.
