What specifically are you confused about?  Did you check the docs?  
I don't know why you'd do it that way when you can write:

  object main_module(handle<>(borrowed( PyImport_AddModule("__main__"))));
  object main_namespace = main_module.attr("__dict__");

instead.

Certainly not.  Calling the interpreter inside an extension module is normal.
