Because people who usually resell old games to fund new game purchases will have less disposable income available.
If console makers / publishers take a cut out of used game sales, then that is the exact amount that will not go into buying new games.
Logic, isn't it awesome?

PS.
Percentage totally made up, like that other publication that used it.

I cited the source, wich was serious, so I only want to ask : Can you read ?
