I think this is far from obvious as well.

I looked back at 2010 breakaway and found an 84" cylinder that year. I really doubt the GDC wanted teams to become 84" ball blockers--they likely figured many people would tilt while climbing and would still need to reach up the 84" to the bar. that would imply they felt the cylinder tilts with the robot.

I also don't see how that picture clarifies the OP question since that robot is not clearly tilted.

I think I'm right at 50:50 on this one...

EDIT:
answered:

Q. Is the 54 inch envelope diameter (figure 3-5) orientation sensitive ie is its axis always vertical regardless of the robots axis ie such as when the robot climbs?

A. The vertical cylinder specified in [G23] is not coupled with the ROBOT'S orientation and is always vertical.


Q. Rule G22 places height restrictions "in relation to the ROBOT." Does this apply to G23 (horizontal restrictions)? When climbing the pyramid, extending an appendage "out" from the robot but "up" in space might extend past the cylinder if it is taken relative to the robot, as opposed to the ground.

A. The height requirement in [G22] is relative to the ROBOT. The horizontal volume requirement of [G23] is relative to the FIELD (see answer to Q15 ).
