"We had that game with 20 to go, but the energy was really good from Linton today," Reweti said.
"There have been a couple of times where we haven't finished off our games when we've had a good, comfortable lead."
Boxon done well to get into the game after an error-riddled first half performance saw them heading for the sheds 16-6 down.
The Cobras showed good line speed early on, exhibited by five-eighth Shadow Wirori, who intercepted a Boxon pass and ran 60m before being run down.
That break busted Boxon's structure, and the Cobras shifted the ball wide to winger Troydon Lochore, who scored in the corner.
Lochore was a handful in the first half – he set up another try with a run through the middle, busting some poor tackles and leaving the defence in tatters.
Eventually Lochore was brought down, but the Cobras shifted wide to Wirori, who had a world of space and could have walked his try in.
In between time, Cobras centre Tevita Faukafa had scored on the back of a 40/20 kick and Boxon got their only try of the half through block-busting back-rower Ritchie Graham.
Reweti told his team to adapt at the break.
"I just told them to adjust to the ref, get back to how we play and remember our structures.
"We did do that in the first twenty minutes of the second half, but then we fell away."
It was a new game after the break and the Cobras discipline let them down.
They gave away back-to-back penalties and Boxon's monster prop Shade Heta made them pay by tapping the ball and muscling his way over the line.
Boxon's tryscorers were beasts – two big runs from Heta and Graham from the kickoff paved the way for Corey-Lee Robertson to gather a grubber kick and score.
At 16-16 Boxon did not take the foot off, as winger Tai Logadraudrau scored, then hooker Steven Aue piled the pain on the Cobras with back-to-back tries.
It was 30-16 and Boxon might not have worried when Faukafa burst through two defenders and ran 50m to snatch one back for the Cobras.
That thought changed after the kickoff when the Cobras worked their way back up field and Wirori sliced through the Boxon defence to score another.
The Boxon team from the first half were back, and in the blink of an eye Corey Governor had scored for the Cobras and converted it to give them a remarkable 32-30 lead.
Under pressure, Robertson tried to pull off a big play for Boxon, but his kick went out on the full and the Cobras punished the mistake by scoring through centre Nikolao Ioane.
Governor's conversion was going over, but the ball began to bend and collided with the post – leaving Boxon still a chance to tie.
Robertson gave them a shot when his kickoff forced an error, but it was over moments later as Aue passed the ball straight to ground and the Cobras pounced on it to complete their stunning comeback 36-30.
Reweti said it was back to the training paddock for his team.
"We'll work on executing our game plan, because when we do, it works.
"We march up the field quite easily, what we do off the back of that just has to be better.
"We let it slip away today," Reweti said.
