The UTR50 defined orientation is a character property.  It only
affects the intrinsic orientation of a character.  At least as I've
understood the WG discussions in the past, it will only affect the
behavior of the 'upright-right'.  When 'upright', or 'sideways-xxx' is
specified those represent explicit overrides on the underlying default

In vertical text, the element below appears rotated:

<span>Hotel Wonderland</span>

In vertical text, the element below appears upright:

<span style="text-orientation: upright">Hotel Wonderland</span>

But I can definitely see how reading the current CSS3 Writing Modes
spec could lead you to see things as you do, I definitely think the
explanation could be clearer.
