So, uh, am I reading that right? One part is “use array of structs for ECS” and the other is “use struct of arrays for ECS”? Really?

Yeah the optimization is similar to the realization that array-of-structs can be the faster memory layout if you use all/most of the members of the struct. So you organize memory by archetype rather than keeping the components separately.
