I mean, they were rather strongly related until Shadow Play retconned what the Pony of Shadows was.

"When I was just a filly, Granny Smith told me of an ancient legend. When Nightmare Moon was banished, not every last bit of her dark magic went with her. Granny used to say, when night falls on the castle, that magic takes the form of... the Pony of Shadows!"

- Applejack, Castle Mane-ia

The confusion is understandable in this case.
