I agree that an explanation would be an interesting glimpse into the designer's process. However, the author clearly put more thought into this than simply "rearranging elements around a page."

The "Quickstart" link was removed, a menu was created below the main graphic with various uses described, applications (and their practicality) were featured much more clearly than in the previous design. All the changes I noticed seemed thoughtful and intentional, both from a design as well as a marketing perspective.

So sure, an explanation would certainly add to the post and spur more discussion. However, the author has demonstrated that they know what they're doing and should be spared a lecture on what design is or isn't.
