It's any angle that's flatter than the Rotated Shoulder Turn (10-13-C). A Rotated Shoulder Turn is when you make a turn that's perpendicular / 90 degrees to the spine. So anything flatter than that would be classified as a Flat Shoulder Turn. So it is not "as flat as possible".
10-13-A is very common, keeping in mind my comments above. Remember the photos are trying to illustrate the Flat Backstroke Shoulder Turn, and it's emphasized for clarity.
A flat backstroke shoulder turn is simply turning your right shoulder back to the plane in the backstroke. Like Tongzilla mentioned, that's opposed to turning it perpendicular to your spine.
It feels like you just "pull" your right shoulder back as you pick the club up and then you're perfectly set up to drive it right back downplane.
Much easier to accomplish with the right forearm pickup. That solved my shoulder turn issue. Prior to using the right forearm takeaway, I was using the rotated shoulder turn in the backstroke.

The right forearm pickup supplies the "vertical" motion in the backstroke and the shoulder turn provides the "horizontal" motion. Pick the club back, up, and in while turning the right shoulder back to the plane.
I noticed that very thing on the range Monday, except I came at it from the other direction. This flatter shoulder turn help me feel and execute the RFP.
I went from playing pretty well this summer to about the worst ballstriking I've ever had during the last couple weeks. I used to have a flatter turn, but for whatever reason, I started tilting a little and not turning enough. The (concious) flat turn literally transformed my ball striking overnight. The flatter the better right now, as it is the furthest from what I was doing; I just want to make sure I'm not introducing a compensation.
With a flatter backswing shoulder turn, I've noticed the long clubs are much easier to manage. 2 and 3 irons off tight lies sizzle and soar. Nutting the woods as well. But the same identical 13-B move with short irons is problematic. Feels too flat, so I'm planning on shooting some video to see what's happening.

I've read that thread before, but there's less fog today and this was a great second look...must have searched on the wrong term yesterday.
So did you ever figure out the problems with your short irons? I was thinking the exact same thing at the range! Video was in my plans for this evening.
For short irons -
The solution was not in the shoulder turn. It is fine.
The solution was making sure the right forearm was setup on plane, which got everything else from head to toe set up correctly for the club in hand.
I was setting up fine with the longer clubs, wasn't paying attention to the short stuff.
