If the reasoning is "cmp(actual, expect) makes more sense to humans" then I do not think it is universal. Otherwise why would so many existing test frameworks do it the other way? And that is why I said it seems more like an issue of personal preference than a universal truth.

Was there some objective argument made that I missed?

"Computer, given that we expect B, how does A differ?". Or "Computer, we expect B; does A match it?"

Or any number of variations. I'm sure you will say "but those seem awkward and unlike how I think about it". But that was my point; it seems to be a matter of preference.
