As I see it, with this system power will not ever be fed back into the
grid, anytime there is power at the "service" terminal the generator
will be disconnected by the NC contacts and the ignition will be
killed by the NO contacts...

Wrong. It will feed power back to the grid *EVERY* time the grid power
is restored with the mains switch still on and the genset running.

The generator cannot be started and will not run whenever the main
switch is on.
The generator cannot be started and will not run whenever there is
grid power at the service terminal.

Please don't encourage him.

With all due respect, in this context it doesn't matter if the logic is
"right", the design is wrong. Too many potential fail-hazard scenarios which
are easily avoided.
