Schweser and CFA ethics conflict? conflict, receiving, execution, disclosed, management

Example from Schweser

In return for receiving account management business from Broker X, a member directs trades to Broker X on the accounts referred to her by Broker X as well as on other accounts as an incentive to Broker X to send more account business.

Now this is obviously wrong..

the comment is

This is a violation if Broker X does not offer the best price and execution ""or if the practice of directing trades to Broker X is not disclosed to clients"". The obligation to seek best price and execution is always required unless clients provide a written statement that the member is not to seek best price and execution and that they are aware of the impact of this decision on their accounts.

This makes it sounds like you can direct brokerage for referral as long as clients are notified which seems to be wrong.

CFAI says

An Investment Manager may not allocate a Client's Brokerage based on the amount of Client referrals the Investment Manager receives from a Broker.

Am i missing something here or is schweser wrong here?
