I'm assuming you're referring to the map in column "a" of the graphic. They didn't mislabel them. The Cascades are nearer to the coast. Same with the Sierras. I think what's got you mixed up is the perspective of the map. It's slightly oblique, which shortens the apparent distance between the mountains and the coast. It's not a terribly good graphic. There are no state borders, yet the map is clipped in a way that gives very little context.
