Convergence artifacts are due to the algorithm converging poorly. This is why it's a "pity" the interesting structure you see in the picture has nothing to do with the distribution of numbers and is just a bug in the algorithm that happens to look nice.

So no, it's not like the Mandelbrot set. It's more like if you wrote a script to visualize the Mandelbrot set and created a bug that made part of the visual you created look like there was an interesting structure by accident, then shared your pictures with a wide audience going "look at this interesting structure I found in the mandelbrot set!" and then someone replies on Twitter with "you have bug in line 124 and when I correct it the structure disappears". Which is why it's a pity.
