That is a vrey good strength feature which adds an element of resistance to bending and twisting. These added solder points help prevent the loss of the center setting which can happen on rare occasions. Of course, the main reason for such a design is for the sake of the design itself. They resemble the flying buttress effect on European cathedrals. Those buttresses also add strength to the buldings they help support. Those were an early method to distribute the load of the high roof onto the sides of a building that would have otherwise required many more obstructing interior columns to keep the high roof supported.
