Aug 7, 2019 at 10:40 comment added YCor "the ultraproduct of all members" does not mean anything. Given a set $X$ of sets, I think that "The ultraproducts of $X$" can indifferently mean all ultraproducts $\prod^\eta_{A\in X}A$, for $\eta$ ranging over ultrafilters on $X$, and all ultraproducts of all families $(A_i)_{i\in I}$ of elements of $X$ with respect to all set $I$ and ultrafilters $\eta$ on $I$. Here in this papers all structures are finite, and "infinite" just means we consider only those ultraproducts that are infinite, i.e., restrict to $\eta$ such that $\lim_{i\to\eta}|X_i|=\infty$.
