That was true at that time (2.2 initial), but not now. See
Revision 26220 - Modified Sat Apr 6 01:05:01 2002 UTC (4 years, 11 months

- Changed new-style class instantiation so that when C's __new__
method returns something that's not a C instance, its __init__ is
not called. [SF bug #537450]
The documentation should be updated to reflect this change.

It's in typeobject.c, function type_call
