The number associated with System is not the size of the system heap.  It is
the total RAM less the RAM used by running applications and the RAM
available to run additional applications.  (Under System 7, it includes the
memory used by the Finder.)

It does include the System Heap, but it also includes the RAM cache, memory
allocated towards background tasks, the memory beyond 8Mb (when running in
24-bit mode), etc.
