I know but the orbit module doesn't go through re-entry it was also designed to either bring cargo or serve as temporary living / scientific quarters when the Soyuz was used for manned orbital flight rather than a ferry to Mir or to the ISS.
But and it's a big but the space is separated which means a great deal this means that the Soyuz orbital module can be used to bring cargo to the ISS the space in the Dragon capsule is really just wasted, there's no way there will be cargo in there no matter how well tied down during lift off no human flight program ever had anything in the cabin that wasn't a part of the space craft or needed for life support / emergency, so it's still a bloody waste of space.
