This was a fad on American courses in the late 1980s and into the 90s, so that marketers could write that the course "has a double green, just like St. Andrews". Jack Nicklaus and Tom Weiskopf must have built a dozen of them. I don't want to make myself go back through all of them, but one I remember was The Club at Morningside, in Palm Springs, because it made the traffic pattern around the green very awkward for golf carts.
That's one reason I decided I never wanted to build one; the other reason was that I felt that apart from St. Andrews, they are more of a gimmick [for marketing value] than a function of design. But, I did build one, which has not been mentioned yet; I got outvoted there. It still annoys me.
