If you watch when he is shooting the scene, he takes multiple shots while positioning. I suspect that he is stitching them together for an ultra-high-resolution image. In the "best of Monochrom" thread on this site, there are some fantastic stitched images made with longer lenses (90 'cron APO?) that have the shallow depth of field of long glass, but the wide field of view of a 35 or 24mm lens.
I don't believe he did any stitching, I doubt he would have to. Platinum Prints do especially on Watercolour paper do not need the highest resolution images a lot of details are getting lost in the paper fibres furthermore the print doesn't look much bigger than 8x10 inch a size the monochrom non stitched files should be able to handle with plenty of details.
I personaly just thought that it was funny that he worked in a lf way with a modern interpretation of a 35mm RF camera only shows how versatile this camera is.
