The principle of grouping is used to help the reader understand better an image this loosens up confusion. Without grouping you can have sensory overload. The before image capitalizes the idea of confusion. You have two images next to each other along with description on the other side. One could not just look at the picture and understand. To combat this I separated both images, next to each image is the description. This cuts the confusion and helps the reader to better under the image and the context that goes with it.
