If you look at the water flow in the filters and VeipaCray's suggested layout, you'll see he puts carbon before biomedia. I believe the idea is to add an additional trap for debris after the sponges--because you'll be changing that monthly and to pull any chemicals out that may affect bacteria.
Fluval has carbon after biomedia, because it will help in clarifying the water.
My guess is the recommendation here of carbon first is because of the heavier waste load of turtles. My suspicion is that it likely doesn't make that big of a difference.
