I'm not sure about all of the returns on the same wall as the deep suction and the skimmer on the same wall like that...how is the water going to circulate? Mark recommends returns across from the skimmers...
Yeah it doesn't make common sense to me either, however, I talked to the PB this morning. I'll attempt to summarize his explanation, but there is a clip on youtube from one of my favorite moves that does this quite well....

PB's explanation: We used to install them like that. Water in a pool will start flowing in a circular fashion. If the returns are on the opposite side of the pool (remember mines a long rectangle) water will flow toward the skimmer and then run along the side of the pool both towards the deep and shallow end. Causing leafs and floating debris to be pushed right by the skimmer. He said through testing he found that returns on the same side as skimmer cause the exact same effect but the result is floating debris hit the far wall and then where the two opposing flows meet in the middle they start floating right toward the skimmer.
He said my far left and far right eyeball would be pointed towards the deep and shallow end. He didn't say where the eyeball in the middle would be pointed. I'm guessing down.
On this particular job doing it like this sure makes the trenching and plumping easy....that would seem to work both ways, to his and potentially my future benefit. Meaning there is really only on side of my pool deck that would ever need to be torn up to fix and up the pool plumbing/lights/skimmer/main drain.
Remember he did tell me that he recommended the main drains be installed in the floor (so you can blame that on me) I had to sign a Change order on that and the extension of the first step to 3' from 2.5'.
They showed up at 6:30 this morning and were shooting at 7:30. He said they'd be done by 10 or 11. He was going to let the pool harden up for a couple of days before he comes out to finish plumbing and start the bottom/back fill/grading.
I asked if i need to keep it wet, PB said No, Shotcrete foreman said right after that don't worry we put it down with enough water.....whatever that means.
