For all of my tongue's battle scars, I really enjoy this pepper. Virtually everyone who tries a decent phenotype of it echoes your sentiment that it's hotter than the average hab.
Thoughtful review as well. I'm always most informed by any pod review that extends its descriptions of flavor profile beyond the familiar terms. I mentioned this in another thread once where there generally seems to be a poverty of terms used to describe chili flavors, so the net effect is this failure to distinguish things by taste descriptions alone. Certainly one part of that is no faut of the reviewer in that a species (say chinense, for example) impart familiar hallmark notes throughout the family varietals. But there are subtle distinctions to be sure. I think the more refined our palates become outside of pepper eating the more our subjective vocabulary improves.
This all said, I agree on the citrus-forward taste of the Fatalli. The few I've eaten had a kind of bursting satsuma mandarin quality right away followed with a surprisingly assertive heat.
