Interesting thought, as when a similar field vs. robot question was asked on the Q&A last year, the response specifically defined "vertical" as in relation to the robot. In fact, virtually all such questions with regard to both orthogonal axes were deemed to be in relation to the robot that year, and in several others I can remember offhand.
Note that this is not to say that 2013 will be the same as 2012 or any other year, only to point out that the GDC has written in similar ambiguity in the past and ruled it robot-centric. It was really the only logical approach for many of the 2012 questions; this is significantly more ambiguous.
