No, the Cambridge article covers why the light receptors are back to front, not why the image is sent to the brain the wrong way around. It explains why there is no distortion in the image (when science originally thought there would be), because each cell channels the light down. The image is sent to the brain the wrong way around because of the lens used (see picture below)

The current explanation for this by Evolution is that the eye started off more like (A), which didn't invert the image, and then evolved into (B), developing a lens and flipping the image. However instead of rewiring the eye to make the image send to the brain correctly, the brain evolved to interpret the picture the other way up. The Evolutionary step to (D) also kept the brain's interpretation.
The "better" design is quite obviously rewiring the eye, because all you would have to do would be to rotate the retina (and all connections going into the optic nerve) by 180 degrees. This would mean the picture is sent perfectly to the brain, where no processing is needed. It's a simple change that makes seeing a much more efficient process. Of course, Evolution doesn't work like this.
