Point taken

In reality Fuji mosaic doesn't eliminate moire, it just spreads it over different spacial frequencies at lower amplitudes. In particular, it produces lower frequencies which wouldn't be present in bayer, and though those are lower amplitude, they are more easily visible. The experiment shows how aggressive processing amplified those to the horrible degree.
