The ugly spat from last Friday night stretched into the week when Malthouse was fined $7,500 and assistant coach Paul Licuria $3000 on Monday night for the verbal altercation.
Thomas, 22, said the issue was promptly put to bed by the club.
"We tried to move on from it as quick as possible as a club and a playing group," he told collingwoodfc.com.au after the Magpies' 64-point dismantling of Hawthorn.
"He gets pumped up in the press but that was the week before and already we're looking forward to next week."
Thomas said there hadn't been a focus on "making a statement" on Saturday night despite the controversy and the fact the Pies had been out of form in the past fortnight.
Instead, he said the objective had been to play intense football for the whole game after a costly fade out against the Saints.
"Last week we were pretty good for three quarters but we knew we had to do it for four quarters and we did that," he said.
"The extra day rest was good because we'd had a few short breaks and some hard games with Melbourne and the Western Bulldogs.
"It's hard to say and get a gauge of how much that takes it out of the boys.
"There was a little bit of a freshener because a day is a long time in football so I think that helped."
The Magpies were again off-target in front of goal, spraying eight behinds in the third quarter and 21 for the game.
While Malthouse denied the pace of the game had affected players' ability to kick straight, Thomas said there could be truth to the claim.
"It's one of those things. People miss. You don't mean to but everybody does it," he said.
"With the pace of the game and with where players are having their set shots from … the pace has probably contributed a bit.
"There's no real reason for missing though - it's just something that happens."
