With Classie Brigade certain to hand the lead to the first of the favourites to challenge him had Self Assured got between horses into clear air he could have sailed to the lead and likely victory.
But Orange knew his Cup dream was about to disappear and closed that gap, staying outside Self Assured but with clear air to keep pressing forward and once he got in front of Self Assured it was he who strode to the front, controlled the speed and was far too fast late.
"That was the winning of it," said Orange.
"I could see Mark [Purdon] hunting for that gap and I knew we had to get in front of him or we were in trouble.
"We managed to just get enough momentum up and once we did that we were able to get the lead and after that he was never going to be beaten.
"He is such a wonderful little horse and Ray had him so ready, I just feel for him that he couldn't be here."
It was not from a lack of trying as Green applied twice for a travel exemption but was turned down but seemed to be enjoying himself at a small post-race party outside his stables.
"It was very emotional to watch," Green told the Herald.
"It is my biggest moment in my career and it is not until you feel that relief after that you realise how much stress it puts you under."
Green has more than just a career-defining victory to be proud of, his wife Debbie having picked Copy That out of the sales for just $7000 as a young horse.
"He was a lovely little colt and she liked the way he walked so it was her choice," he boasted.
Most of the big Cup players will likely back up in the NZ Free-For-All at Addington on Friday and while Covid restrictions may ultimately decide Copy That's Australian plans, Green suggested the Miracle Mile in Sydney in March is a logical target.
While Purdon lost that early tactical battle in the Cup and had to settle for second with Self Assured, he didn't lose many others yesterday as he co-trained five and drove a remarkable six including Franco Indie in the A$170,000 Sires' Stakes and Oscar Bonavena who finally produced something like his best winning the NZ Trotting Free-For-All.
As good as Oscar Bonavena was in his Group 1, the performance of Franco Indie was special as he overcame sitting parked to suggest he has Derby written all over him for next season.
On a day when the crowds couldn't be at Addington, they missed a treat in not seeing him race.
