If they are allowed to overlap, then they might as well have unlimited shops per structure. I don't like that situation.
The actual number of rocks present was always intended to be the limit to the production available there. That limitation fell apart at some point along the way.
In the tile terrain days, a tile had 0-4 rocks. That determined the number of mining processes you could run. Likewise, the number of trees limited the number of logging processes. You could not put two buildings on the same tile.
