After the extruded tube of clay (with core holes) is cut, the bricks are set face up and any glaze applied before firing. Some bricks (probably not now) could also be fired twice, before and after glazing. Dr. Judith E.

It is extuded with the holes as a long tube and then cut into bricks. Can't quite visualize that, but I don't need to. But then, how to they apply the glaze to one side?
