> In what context?

This is a great question for the article's author, I think! They give very little information as to when this class of optimization makes sense, and because it's much more complex to implement than the AoS -> SoA transformation in the general case when the total ordering of enums is important, either a case-study or some general heuristics as to when this transformation is worth the effort would make the article more useful and interesting.
