It uses a different serialization mechanism than PLO. From the POPs: Programming Notes:
1. COMPARE AND SWAP AND STORE may be used in conjunction with other COMPARE AND SWAP or COMPARE DOUBLE AND SWAP instructions to manipulate locks, queue pointers, or other fields that require interlocked updates. 2. COMPARE AND SWAP AND STORE should not be used to manipulate fields that are also manipulated by PERFORM LOCKED OPERATION.
