The axis i believe they're referring to is the axle. So then I interpret it as saying the wheel must remain vertical, relative to the ground, but doesn't necessarily need to maintain its orientation relative to the robot chassis.

I could be misinterpreting this, so if it a serious issue for your design it would be best to contact FIRST for clarification.
