Ok so the top switch represents the single throw of the relay? So current needs to pass through pins 1 and 7 for the switch to be flipped?Welcome to AAC.
That figure is horrible. There are connections that are laying on the grid lines making them nearly invisible.
This marked up figure might help you understand what is going on.
Ignore the blue and green dots on the last added line, those are handles from the markup program, I accidentally left them when I took the screenshot.
