It's hard to see in an image, in the battle himslef is easier, but the back wall is 1 block forward the back "ramp"
You can see a brown line bewtween both, thats the void that you can see in battles, and with the movement of the battle system you can see that the wall moves slower than the upper part of the ramp, because is closer the camera.
