Dunno much about the submarine, but from an aerodynamics point of view, I always imagine it as a canard and elevator configured aircraft, like the Su-37.

With the forward plane pointing down (leading edge down), the angle of attack at the dive plane is decreased, resulting in a decreased lift, so the bow will sink.

With the aft plane point down (trailing edge down), the angle of attack at the dive plane is increased, causing an increased lift, so the stern will rise.

A common misconception comes from how you define up and down. Also from an aerodynamics point of view, we use leading edge/trailing edge to describe elevator/canard position. There's also a convention in body systems whether leading edge/trailing edge should be used. From the look of dive plane indicators in Wolfpack, it seems that the forward plane uses leading edge and the aft plane uses trailing edge to describe up/down angles.
