In the layout diagram on the site, pin 1 is connected to ground as some octals have pin 1 the shell which grounds it well. For pin 6, that is simply wired as a patch point for the 1.5K grid resistor. You could wire that directly, but for people using the 5F2A circuit layout board, it is generally a nice connection point. It helps keep wires separate and maximizes the distances between them.
So pin 1 is a ground, pin 6 is just a “terminal” for easy connection.
