I've seen much more where the short-game, low-cut area around a green melds into the next tee with no change in cutting length. Gil Hanse seems particularly fond of this type of feature and I have to admit a real fondness for it, as well.
It certainly beats all heck out of walking 30 yards to a cart, stuffing the clubs back in, and then driving some appreciable distance to the next tee.
I think it has to do with a feeling of continuity, of completness, of integration, and of connection.
Is there anything more convivial than the waits that sometimes take place between groups on this type of course, where perhaps the folks behind wait to hit their approach until the group ahead hits their tee shots and is safely out of range? I think it adds to the sense of camaraderie and companionship between golfers sharing a course, and one of the reasons the Old Course is such a shared, communal, quasi-religious, spiritual experience.
