The first effective use of this type of cross-bunkering (that I saw) was Nugent's Forest Preserve Nat'l. I think it's the 5th or 6th hole, a par five, with this complex, short and left of the green, placed at a diagonal. The height of the bunker's top edges serve to obscure and creates the deception that they are greenside. In reality there's plenty of room over them, and is a preferred angle of attack.
Baxter used the same effect on a short par 5 here at Riverview.
