In the 1934 Tournament Program, the greens shapes for 4 and 6 look like mirrors of each other.
Neil, you made a key point about Mac's hole descriptions. He was already dead when they held the first Masters. The comments are so identical, it looks like ANGC edited Mac's AG article, published in 1932, two or so years earlier.
BTW, once again Roberts and Jones seem to show their dishonesty. They don't pay Mazkenzie, they use his course (to great acclaim) to hold their annual major tournament -- one they counted so important they turned down a U.S. Open to hold it -- even after he is dead they use what he wrote about it to help promote/describe the tournament/course, and they change what he said to boot.
