It is a diagram and it is very clear, even if you have to trace it.
There is no metallic conductor between the transformer neutral and the
house earth ground

Thats right, but it leaves out part of what is said. The earth
connections ARE only at the two ends, but good practice and my power
company requires a metallic path, as well.

I disagree- the SPG and household wiring are inseparable because all the
conductors in the house are related to ground by the neutral and safety
ground wires.
