This flag specifies the number of processors that ctest is allowed to use
in regression tests. I am guessing the other flag is MPIEXEC_NUMPROC_FLAG.
That is the string that ctest uses to tell mpi how many processors to use.
It is "-np" in many mpi implementations. Neither affect anything other than
the regression tests.

I suspect you are just forgetting to run pvtkpython under mpi.
For example:
bin/pvtkpython
/Source/VTK/devel/VTK/Examples/ParallelProcessing/MPI/Python/ParallelCone.py
numProcs is 1

mpiexec -n 2 bin/pvtkpython
/Source/VTK/devel/VTK/Examples/ParallelProcessing/MPI/Python/ParallelCone.py
numProcs is 2

mpiexec -n 16 bin/pvtkpython
/Source/VTK/devel/VTK/Examples/ParallelProcessing/MPI/Python/ParallelCone.py
numProcs is 16
