I think the idea is: they both pick “heads” because it’s more obvious than “tails”, it’s the most salient “landmark” in the territory (like the information desk).
I wonder: is heads a “landmark” all around the world, or is tails an equally obvious choice in some cultures? (It seems like the kind of thing that could be arbitrary.)

Hmmm… I’d guess whatever they call the “main” side is what we’d translate as “heads” (or “obverse”)
