While it's obvious that you are correct, I'm more interested in understanding why it happens.
On my first winter trips to AZ in the 80s, I played Mesa CC where my parents had recently joined, and they had dormant Bermuda fairways with overseeded greens. The course was built ~1950 and features mostly back-to-front green slopes.
So you had really firm and fast fairways with very firm overseeded greens. In between the runoff from the greens made the approaches ridiculously soft. Land 15 yards short and you were probably over the green, land on the green, same. Land 5 yards short, stop dead.
These days, with overseeded fairways, the problem is less noticeable, but back-to-front slopes are always going to make it hard to keep the approaches firm.
