Rule clarification that appears to say robots over 30 inches cannot climb?

[computerish]

There's a Q&A from today that seems a bit odd:

Q.If you have a tall robot are you in more than 2 zones simultaneously?
A.Yes, depending on the height of your ROBOT, it is possible for a ROBOT to occupy more than one
Level at a time.

Admittedly they didn't really answer the question, since they said "more than one level" instead of more than two (as was asked), but the answer here seems to imply that a robot taller than 30" is automatically in three zones (ground, 1, and 2). If this is the case, it would be virtually impossible for any robot to climb unless they inchwormed up the side.

Any clue what's up with this?
