The reference point is the box, or if you would like 0D reference point, simply use the center of the box.
In the first, the red "car" is above the center, in the second, the red "car" is below the center, etc.
I am not sure who you are quoting when you write the words "context-free" in quotes, but nonetheless assuming that person means "objectively", then I totally agree with your above statement.Not a quote. It's the "so-called" quotation marks. And no, the idea isn't a subjective/objective ditinction. It's a context-free/context-dependent distinction. In general context-freeness/context-dependence can be either subjective or objective. In this case we're talking about something objective.
