This subtlety hadn't occurred to me before, but I actually have a use
case for it! I have an in-car phone holder that happens to work
better with the phone upside down, so that the USB connection can be
on the left.
So yes, it would be better if a "prefers-portrait" app (like tangogps)
could be shown in either -o 0 or -o 2, depending on actual phone
position.
