[OCCRA]: Ball manipulation

[Agentarrow]

According to the OCCRA rule book, Holding a ball is defined as "off the carpet and at least partially supported by a robot or human player". Later in the document, this rule is stated:
"Robots must not have the design capacity to HOLD more than five balls at a time and are not allowed to possess more than five balls at a time during a game. This is a judgment call made by the refs: if they feel that a robot is deliberately controlling more than five balls at a time"

Does this mean that a robot cannot push a ball around on the carpet whilst holding 5 balls? or does possession in the stated instance mean actually HOLDING more than 5 at a time?
