Winger Jermaine McGillvary and England forward Brett Ferres both scored hat-tricks in a second-half onslaught as the Giants ran the Dragons ragged to complete the double over them, but the contest was lacking in intensity with both defences falling off tackles at an alarming rate.
"We just did enough," Anderson said. "I thought in the game as a whole there was a lack of intensity from both teams."
He added: "I said to them at half-time they had to make a conscious decision about what they wanted from this game - did we want the game to be 40-30 either way or did we want to put 40,50, 60 on a good team because we knew we were capable of it.
"Thankfully we made the right decision, although I still thought even in the second half there was low energy. When we were scoring tries, we were walking back to receive kick-offs.
"There were strange emotions. I am sat in the stand kicking chairs wondering what's going on here and you look at the scoreboard and it's 60, so we obviously did something right."
Some of the gloss was taken from the Giants' win by injury to Wales captain Craig Kopczak.
"It's a potential ruptured bicep so we hope it's not as bad as first feared," Anderson said.
The Dragons scored four unconverted tries but coach Laurent Frayssinous could not hide his disappointment over his side's lamentable defence.
"Even in the first half we scored some tries because their defence wasn't great," he said. "But our defence got worse, from the first minute to the last. You win a game with your defence but something was wrong for us tonight. But credit to Huddersfield, they are a good team and they were too strong, too fast for us tonight."
