Actually, it chops the top 5% of 5 minute transfer averages off in a given time period. The highest remaining transfer number is what you get charged for. (Thats the way it works for Cacti - a better program than MRTG)
I used to run a hosting company a few years back. It was very useful way to bill clients who had bursty traffic. I had to buy a specified capacity, and if the clients wanted to be able to burst, I had to make it available for them.
These days, with bandwidth nearly free, I dont know if it makes as much sense.
