I guess this is where differences of interpretation come in and FIRST probably needs to clarify. Most of the people that mentioned anything about this rule would interpret a robot hanging from another which is hanging from the bar as not scoring points. But I would definetly agree with nic_radford. At first reading of this rule it seems obvious (to me) that a robot hanging off a robot which is supported by the bar is also supported by the bar- a transitivity of sorts.
