My take on this subject is that the Sphinx wasn't carved when the idea of Duat was formed. It was rather carved much earlier and perhaps the ancient egyptians incorperated the sphinx into the fifth division of the Duat because it was there at Giza. The second Sphinx in the fifth division could have been placed there because they wanted it to be more symmetrical.
