Just plain sloppy work in my not so humble opinion.
That drives me nuts too and I see that often in purchased books. I'll go through and delete all the identical images and use just one for all chapters and drastically cut the size of the book once compressed.

But the image within the epub itself doesn't need to be the full 1440x1050 pixels. It can be 800x600 and the code in the book tells it to display the cover at 100% of your reader's screen and it looks just as good as if it was 1440x1050 pixels. For the few minutes you actually see the cover, it's silly to include huge images thinking it will "look" better on an e-ink display. Even on a color display, the same coding can be applied and no one would see the difference if done correctly. You can use the cover as your screen saver while the reader is asleep and it will still look perfect.
