Looking up the balance of these addresses is an information leak as if blockchain.info was keep logs it would show you had an interest in these addresses. So don't use the "Recover Intermediate Addresses" tool unless there has been an error with a transaction. What limitations does it have? Shared Coin can never completely sever the link between the input and destination address, there will always be a connection between them, it is just more difficult to analyse.
