That is a good insight which is not so obvious. The author should have written a white-paper for more credibility.
But I would not be surprised if the actual generation of a new painting takes less than a second as generative networks can be run quite fast to generate new image. I assume the author had the challenge of creating this new "generated" content on-the-fly in browser from the trained model and hence just loads from already generated thousands of images for convenience of the user-interaction. But yes it is a little misguided approach for Karma.
