Mark,
This a concept that Maxwell used a lot. At just about every course he seemed to use this on multiple holes. I think this approach is similar to some things that Fazio does on his courses that I've seen (all 2 of them)
. Maybe I can add some additional depth to some of your examples.
The third at Dornick has had the green moved from the origional location. It was originally further to the left and closer to the creek. It also was a version of a punchbowl or alps. I'm still trying to determine which because the one old photo I have is difficult to decipher. But it would provide further evidence to your point as the outside angle would provide an even clearer approach.
The second at Southern is probably one you might want to exclude from this as the approach to the hole today is entirely different from the original due to tree growth and not of Maxwell design. The hole originially had much of a bottle template design where the left and right sides provided different challenges.
The twelfth at Southern Hills is also different from the original design intent. Initially you could drive along the left over the bunker and have a shot into the length of the hole, but you still had a clear view into the green if you played out to the right. You just had a much narrower target and had to clear the creek.
I will say that I think that Maxwell liked to use this on several short par fours. The eighth at OKC is a great example to accompany the tenth at Twin Hills that you have included here.
