it has become unfortunately common in marriott hotels in the (western) US, specifically the current generation of residence inn; and i think i've seen it in new towneplace suites as well. it's entirely a form over function decision: you end up with cool air wafting in while you shower, and you end up with a wet bathroom floor (including a soaked floormat).
the same hotels have a kitchen sink tap which has hot/cold selected on the vertical axis, with no indication of which direction is hot/cold.
