Reddit doesn't actually store the history of your edits, only that you edited it (which is why, when you scrub reddit history, people recommend editing it because then your posting is gone except for say a backup). Facebook, however, allows you to see the history of posts so if someone edits it you can see what they originally posted. I don't think editing a Facebook post first would have the desired effect.
