Not understanding video explanation

I assumed that some Poems are thematically pluralistic was the first rule, some sonnets are pluralistic was the second rule and all sonnets are short poems was the third rule. Thats how I diagrammed it since that is the order it is written in the answer choice. How can it be that "all sonnets are short poems" is the first rule? It seems the order IS important since its apparently most parallel to the question stem. What am I missing?

Let's look at the initial statements logic. We are told that all Xs are Y, and that only a few Xs are Z. We then conclude that not all Ys are Z.

Let's look at E: we conclude that some SPs are TP, because some S are TP, and All S are SP. in other words, not all Ys are Z, because some Xs are Z, and all Xs are Y.

This is almost identical, the only difference is that none phrases things in the positive and one in the negative, which I wouldn't worry about. They may be in a different order but the statements are logically identical.
