It is also possible that they share our understanding that looking dead and being dead are not necessarily the same thing. In that case leaving food would make sense. As I understand it the burying mostly involves covering with branches and leaves. Again, perfect sense if they might recover, by providing camouflage. Perhaps they need to move on but want to give the maybe not quite dead the best possible chance. Transferring that behaviour towards other animals is not such a stretch.
