"I used my brain and told the boys to wait another 20 seconds.
"It might change a bit. It might be different when you take the unlimited interchange out of the game.
"That's the way it panned out tonight."
World All Stars coach Wayne Bennett said referees will need to police the rule to ensure teams don't exploit it this season especially with the interchange also to be reduced from 10 to eight this year.
"They shouldn't be allowed to (take advantage of it)," he said.
"Once the scrum is packed it's not like you have 35 seconds left. "The rule is to get the scrum packed and let's get on with the game.
"The refs may have to look at their interpretation of it." "I remember watching thinking 'this is not what we want'.
"We were all sitting there waiting for the time clock to come down, that's not the idea of the rule."
Indigenous All Stars coach Laurie Daley admitted it was "frustrating" to witness.
"At one stage I think they waited for 20 seconds (to pack a scrum)," he said. "It was frustrating watching it.
"I don't know what the answer is."
