I can't speak to every implementation of smem, but I have used it quite a bit under SLES and Ubuntu, and it always seemed to do what it says -- USS is unshared (process-local) memory and PSS is that plus the process's portion of shared memory. (The sum of differences between PSS and USS == total shared memory.)
