Reason, on mountain biking, you need fast clip on on a up-incline, and also it is more secure when you are bombarding rough downhill.
On road, usually you have little more time to put your feet into power grip and has benefit of using any shoes you like.Also if it is a long uphill like 5 or more miles, you can always get off the bike and walk VERY comfortably, instead of standing still.
