Henry most likely changed some things. Perhaps Henry simply wrote that the urn as seen in 3x22 contained Ingrid (who's based on the original snow queen, which is public domain), not Elsa, and she starts looking for Emma because Ingrid thinks Emma could be her younger sister but not for Elsa. This way the story plays out pretty much the same but all the Frozen stuff is removed. The 4x07 flashback could be pretty much the same (Ingrid killing her sister), except without Gerda as a character (Ingrid could be imprisoned by the Duke of Weselton, except he'd have a different name). Then Ingrid kills herself because she regrets what she's done, or something.

Same for Cruella. Just change her name and appearance and that's it. Her story on the show has pretty much nothing to do with the original book anyway.

Aladdin and Jasmine's story was pretty much pointless to Emma's and Henry's, so he may have ignored that, or maybe he just used the Arabian Nights version of the story and mentioned the "savior/shears of destiny" stuff.

Or maybe the curse simply made Henry publish his book under the Disney brand, so that's how.
