Stygian wasn't turned into the Pony of Shadows by the Nightmare Forces, but by the Well of Shadows or whatever. Anyway, the pony of shadows being a fragment of Nightmare Moon was just a legend (though it's easy to see how it could have originated), and the Pony of Shadows in the other episode is probably just Tirek or Zecora.
