This is a very good way to do it and get them lined up correctly. But the cornerstone gets added with the second side, whichever side you do second.
Apply sashing to one side. Then apply sashing to second side, with or without a cornerstone. These added sashes just add inches to your block, and in the end you just sew blocks together and that's easier to line up and get the seams matched.
