Since the crash mostly affected the US (see all the Europeans wondering what the crash was), that Nintendo reviewed games only for the US/Europe is appropriate.
Also I'm not sure you read my whole comment -- anyway they wanted to shovel out crap themselves, refers to Atari shipping lots of crap games.
I don't think Nintendo released that many crap games to the US, and they also didn't realease too many, 17 at launch in 1985, 10 in 1986, 9 in 1987, and then fewer per year after that. Atari released 22 games in 1982, in addition to the flood of third party titles that were released that year.
