IMO it's deliberately misleading.  The following three layers are
spurious and have no analog on the Cython stack:
   Python code to provide a clean interface
   Handcode C++ Integer class
   GMP's C++ Interface

A more honest comparison would list 3 layers for SWIG vs. 2 layers for Cython.

I don't have a hard time believing that Cython is a better choice for
fine-grained access to C/C++ code.  However contrived scenarios like
the above don't inspire my confidence either.  I have yet to see a
benchmark that reveals the claimed benefits of Cython.
