Interesting observation. Athens CC also has many holes on which you can't see the botton of the pin. (Nos. 1, 2, 5, 9, 11, 13, 15, 18)
Likewise East Lake (nos. 1, 3, 4, 7, 10, 11, 13, 15 and, depending on pin loaction, 18)
I doublt, however, that Ross courses have a lot more of such partially hidden pins than most. Curious to hear what others think.
