I heard him say the same thing and plenty have repeated it. It's misinformation. He said that he can bend the leather and get it to crease. It seems like he doesn't actually bend the leather as part of his leather selection process to weed that out. I asked an experienced leather worker about it, and he said that with Chromexcel there can be more of an area of the hide that exhibits this behavior, and it can be harder to detect with CXL. Good leather workers can avoid it.
