No, you do not understand the design correctly. The grinding wheel will be mounted in the normal, non-Blanchard, surface grinding orientation. See how I am holding the grinding head in the video.

Although I have used a cupped wheel in the mill for some surface grinding operations. With a CBN grit that can produce very nice finishes but cooling is very important because these wheels are usually built on an aluminium cup and if allowed to get warm they will expand and increase the depth of cut and then produce more heat, expansion and increase the depth of cut and then produce more heat, expansion and depth of cut.....until very bad news.
