Ian:
I has suspected as much with what limited writings I have found and from what you have stated from your work in the past. We have to go by what we find in the field and often this can be very telling and fun to find as well.
Since he was the 'terror' I am not surprised that he would want to keep players on their toes, but to me extending the green further and terminating it with additional bunkers and often a support cast of mounds for a back drop doesn't exactly fit his philosophy? Though I do have to admit it is often a great visual display and I know he was quite fond of that too.
I too find it interesting that he departed from many other architects of his time in creating these back drops and in his use of back bunkering, in the manner he do so anyway, but then again he was clearly an independent and creative thinker and certainly took his own path with design. At least he was consistent in his flashing of bunkers despite their location and this is a tell tale signature of his work I enjoy.
There are two bunkers behind the 4th green at LTCC and if you know the green site it is significantly raised, naturally so, above the landing area and for the most part only the front of the green is visible to the player. The green is narrow and fairly deep and here again are 2 small bunkers behind it, but as one approaches the green you can see distinctive mounding that help signal their presence.
