Two main drains - far enough apart that one person can't cover both - are intended to mitigate the risk of drowning from getting stuck on the drain suction.
This is good.

Thanks, Dave.
Yeah, it's a little ironic that the pool has two main drains, but has an unsafe vacuum port, with no warning info on the valve.
By the way, Tony, I moved your pics to the PF Picasa gallery. I've got way too many threads that have missing pictures either because vBulletin (the forum software) 'eats' them every time I upgrade OR because users used temporary picture hosting services. Since these threads stick around and are read for years, that's a bummer.

I think this is how you would run it "normally". I believe this is what pooldoc described, I just wanted to play with photoshop for a minute
Interestingly, my pool has a similar valve setup. It's capable of isolating skimmer, or floor vacuum lines or spa vacuum lines or combining the three how I like. Same thing for the pressure side returns. I also have two main drains, and also two drains in the spa (one on the bottom, and one on the side of the spa, a few inches from the bottom).
