I guess that is just a recommendation, because exchange addresses might become invalidated for some reason (e.g. exchange uses each address for single depositing transaction, and then simply "forgets" it). There is no way of telling address origin, so I doubt pools won't allow you to use one; they just won't be liable if something happens with your payout.

For example Mtgox changes the deposit address every transaction.

Many exchanges don't have a fixed deposit address for each client.

This means that when you want to make a deposit, it will give you an address and it will log that you are depositing to it. However, when they don't receive anything on the address, the address expires and might be reused for another client.
So when you use the address for mining, it's possible that the coins you get from the pool and are send to that address will never end up in your wallet.
