I am not sure. The brick work was done that way the entire time. They put these wire connectors in the brick that matched up to the block to tie it all together along with mortor in between. After I thought about it some more, I know it was leveled and measured to the outside. He put up metal square posts to run his strings. I guess if you did the inside blocks there would be no guarantee it would be flush to the lines.
