Is __ne__ method autogenerated?

The reference says:

  The truth of x==y does not imply that x!=y is false.
  Accordingly, when defining __eq__(), one should also
  define __ne__() so that the operators will behave as expected.

(http://docs.python.org/3/reference/datamodel.html#object.__eq__)

But I saw different behavior on 3.3:

Could anyone teach me what happen about my code?
