Your link says the heavy baseball and the light baseball would fall at different rates.

My link also says that heavier objects can fall slower than light objects. As in the styrofoam board that was heavier than the small ball yet it fell slower.
In the absence of more detail such as the dynamics of the shapes and the inclusion of air drag or not, it is fair to say that the most correct answer to the "which" question is "both". I would only count the "heavy first" answer as correct IF it included the discussion on air drag, otherwise the correct answer is "both". But that's my opinion and not objectively the only way to interpret this.
Especially given a model that has so many physics articles/material included in it's dataset, it's a pretty big fail that it can't answer this properly.

Baseball's have a standard diameter and shape.
It's theoretically possible that the heavier baseball has a "furry" surface or something like that, but it's such an unlikely case I didn't consider it when reading the paper.

I emailed the authors and they said "there could be some pre conditions we have not presented in the screenshot" and that they would address it when they released a dataset.
Sounds like it's all sorted out now. No harm done.
