I think if I had one of these I would wire them as 2 separate switches, including non derailing. I don’t see a benefit of going any further than that. I don’t want the train to derail going into the switch. If it leaves the switch on the wrong leg that’s my fault and I need to pay attention.

That's my current plan, that's the only way I see it working properly.

I agree, there's nothing that the switch or relay can do to fix it if I screw up and have the exit path set wrong.  However, as long as the relays and switches to their job it will only collide with the oncoming train, but it won't derail or short out the track power!   Come to think of it, if it's going out the wrong path, maybe I want it to trip the breaker.

Your logic here would be correct. I’m not home to check the color as wired on the DZ 1008, but here is my setup. When both Dz 2500s light green, the route is A-A, and the Dz1008s wire for NC powers track section 1 and 4. When both DZ 2500 lights are red, the route is B-B, and the DZ1008s wired NO powers track sections 2 and 3.
If the route was both DZ2500 lights green for A-A and I wanted A-B, or A-C on your diagram, it’s the lower/bottom  switch I would change to red. Track section 1 would remained powered and the DZ1008 for the bottom switch would power NO track section 3.

For a B-A route, the upper/ top Dz2500 would switch to red and its Dz 1008 NO would power track section 2. The lower/bottom DZ2500 would remain green and its Dz1008 NC would power track section 4.

Yep, that's my thinking.  I'm glad I spent a little more time looking at this, I was going to go mount the relay and connect it, but following that diagram would have led to disappointment.   I'm still interested in what Scott will have to say about the diagram.
