We got examined and they cited us for lack of 314a searches on beneficiaries of outgoing wires and originators of incoming wires. We argued with them and they backed down. So, I guess the real answer is, "No, it is not required, but you may have to argue."
Also, be sure you do an OFAC search on ALL parties to wire transfers. (They even indicated that we should search the intermediary bank! We refused on common sense grounds unless it was a foreign bank.)
