Things are changing all the time. If you run prstat then you run ps you get two differtent snapshots of memory. Even if you run them more or less simultaneously they will not examine the processes in perfect lockstep.

Now consider that a user is running 10 different processes which are 10 different programs. However all 10 were written in C and all 10 use the standard C library and the C I/O library. These libraries are mapped into all 10 ten processes. But they are shared libraries. Only one copy actually resides in core. That single copy is counted in the RSS of all 10 processes. Now one of the 10 suddenly wants to call, let's say, strncpy() but the code for that is not currently in core. So it page faults its way in. That increases the RSS of all 10 processes even though 9 of the 10 may currently be asleep.
