I can't find any mention of this in 'Behind the scenes' in the HP fandom.
What I understand is:
In books: There was a 3-way duel (or 2v1 ?) and then Ariana was caught in the cross fire. More info here: What exactly happened to Ariana when Dumbledore and Grindelwald fought?
In movies, specifically Fantastic Beasts 3: The Secrets of Dumbledore: Albus and Grindelwald planned to run away together. Aberforth didn't approve. Both Albus and Aberforth drew their wands, and Grindelwald laughed.
Or perhaps they're actually the same:
Grindelwald still pulls out a wand. And in the movie version, Albus just omits mention of the other details like how Grindelwald used Cruciatus curse on Aberforth.
