Yes, yes. I meant "externally undefined". Any person has an intrinsic
up/down/front/back/left/right defined, so a person is always a perfectly
good standard to use in x3 (as long as they are not in a strange posture,
but let's say they are not). So option 3 is unambiguous.

But option 5 requires an external up/down to be defined so that the
hypothetical person that stands in x2 and faces x3 knows which
way their head should point to.
