Not catching that the screenshots do not represent the actual app seems like a pretty big goof.

It's in Apple's best interest to project a quality image in the AppStore. Quality over quantity.

Apple used to allow screenshots to be changed after the app was approved, so it wasn't necessarily a goof.

They still allow the description and "What's New" text to be changed even after review.

Apple changed their policy on screenshot updating back in January, so I'm pretty sure they approved the app and the screenshots together.
