I always understood Destroy as essentially a kill switch, with the big red fireball just being special effects, not what "really" happens (in the same way as the Star Wars-esque space battles don't match the Codex).

And I'm pretty sure Synthesis does work both ways. Doesn't EDI have the glowing green things as well in the final cutscene?
