I'm also somewhat confused about how you to a line across both cpus for barriers because barriers only have cpu-local effects (which is why we always need a barrier on both ends of a transaction).
I'm sorry if my barrier notation confuses you; I find that it clearly identifies matching pairs.
Also, there is a distinction between "can be visible" and "must be visible"; the load and stores themselves are not cpu-local.
