Both Anas are adaptations of the Wicked Stepsister, but only one is Anastasia Tremaine.

Anastasia (Once) is adapted from the Wicked Stepsister and most certainly based on Anatasia Tremaine, being the daughter to Lady Tremaine and sister to Drizella and stepsister to Cinderella.

Anastasia (Wonderland) is adapted from the Wicked Stepsister and possibly based on Anastasia Tremaine. But that's about it. She isn't Lady Tremaine's daughter, Cinderella's stepsister, and there's no known Drizella in EF.

The writers could even come out to directly say "from the Disney movie", but even as a higher authority, the only similar thing to the Disney movie is the first name.

And we're back to what we were saying with Clorinda and Tisbe. They never said they have absed her on the Disney version. Similar case here.
