Guys,
The intention is that any robot to robot contact occur only within the bumper zone to prevent damage to robots. The bumper zone is tested and evaluated when the robot wheels are on a level surface and bumpers may not be articulated (i.e. moving). If the robot changes robot frame to floor dimensions, I would expect the Q&A would respond that the bumper zone still has to be satisfied. As ruled in the past, if the bumpers are angled, they still had to satisfy the bumper zone requirement. That allows bumpers to be mounted higher on one side of the robot and lower on another side.
While the 2016 bumper rules are very close to those in the past, the only real answer can be obtained from the Q&A.
