We rely a LOT on focus to get depth cues from 2D images. When everything is made to be in focus, we lose depth cues and everything looks wrong. That said, they certainly could have created better example images. Like, I would have placed an object like a figurine on an outdoor table with a city skyline in the background and taken a picture of the object from about a foot away. Normally, this would put the object in focus with the city being blurred, as well as part of the table. It would have made it very clear what they were going for.
