Floating face down is also characteristic of unconscious people, that's why life jackets are designed to keep you facing up. Also direction of how body floats depends on weight of arm and legs. Due to weight tide would tip the body to different position (which is especially the case with mechanical augmentations).

Well it's probably a matter of opinion but for me certain themes if they've got to be implemented and were used numerous times before with similar/identical case and reason then this theme should be grasped from unique perspective or the cloning itself should have different, original nature. For example Planescape: Torment used the theme of immortality that during 80s and 90s was very common (Superheroes, scientific researches etc.). Game itself depicted immortality like something not being worth the deal, like a curse and it was nice, it was fresh and gave people something to think about. What people liked in original Deus Ex back in the day was that cloning didn't have nature depicted before countless times, it did something different than most films, games, books (and probably that's why they are overprotective over that canon).

As for replacement body, it might be the case if they transplanted his consciousness which is probably not the case (though Black Light made me think about it for a moment with Jensen not recognizing his flesh). If they implanted just his memories to the identical body then Illuminati created genetic and memetic clone, copy of Jensen and not a replacement for him.
