First, is ethics only about decision procedures? The existence of the concept of moral luck suggests not. Sure, you can say lots of people are wrong, but to banish them from the field of ethics is ridiculous. Virtue ethics is another example, less clearly a counterexample, but much more central.
The three level hierarchy at your link does nothing to tell what belongs in meta-ethics and what belongs in ethics. I don't think your comment here is consistent with your comment there and I don't think either comment has much to do with the three level hierarchy.
Meta-ethics is about issues that are logically prior to ethics. I reject your list. If there are disagreements about the logical priority of issues, then there should be disagreements about what constitutes meta-ethics. You could have a convention that meta-ethics is defined as a certain list of topics by tradition, but that's stupid. In particular, I think consequentialism vs deontology has high logical priority. Maybe you disagree with me, but to say that I am wrong by definition is not helpful.
Going back to Eliezer, I think that he does only cover meta-ethical claims and that they do pin down an ethical theory. Maybe other meta-ethical stances would not uniquely do so (contrary to my previous comment), but his do.

It may not surprise you to learn that I am of the school that rejects the concept of moral luck. (In this I think I align with Eliezer.)

This is unobjectionable provided that one agrees about what ethics consists of. As far as I am aware, standard philosophical terminology labels utilitarianism (for example) as an ethical theory; yet I have seen people on LW refer to "utilitarian m...
There seems to be a widespread impression that the metaethics sequence was not very successful as an explanation of Eliezer Yudkowsky's views. It even says so on the wiki. And frankly, I'm puzzled by this... hence the "apparently" in this post's title. When I read the metaethics sequence, it seemed to make perfect sense to me. I can think of a couple things that may have made me different from the average OB/LW reader in this regard:
