multiple 2.7.3 versions?

A colleague reports that this python from a recent Ubuntu x86_x64
Python 2.7.3 (default, Sep 26 2012, 21:51:14)
contains a fix of this bug
http://bugs.python.org/issue15212
however, all of my other Python 2.7.3s seem to lack this 'fix'.
I would have thought that for a fix to appear in python we should at least get a
micro version change, but the text here
http://docs.python.org/2/faq/general.html#how-stable-is-python
> The developers issue “bugfix” releases of older versions, so the stability of existing releases gradually improves. Bugfix releases, indicated by a third component of the version number (e.g. 2.5.3, 2.6.2), are managed for stability; only fixes for known problems are included in a bugfix release, and it’s guaranteed that interfaces will remain the same throughout a series of bugfix releases.
would seem to indicate that changes to the spelling of a public variable would
not change even with a change to the micro level so my colleague's machine
should not produce this output
>>>> from compiler import consts
>>>> dir(consts)
> ['CO_FUTURE_ABSIMPORT', 'CO_FUTURE_DIVISION', 'CO_FUTURE_PRINT_FUNCTION',
> 'CO_FUTURE_WITH_STATEMENT', 'CO_GENERATOR', 'CO_GENERATOR_ALLOWED',
> 'CO_NESTED', 'CO_NEWLOCALS', 'CO_OPTIMIZED', 'CO_VARARGS', 'CO_VARKEYWORDS',
> 'OP_APPLY', 'OP_ASSIGN', 'OP_DELETE', 'SC_CELL', 'SC_FREE',
> 'SC_GLOBAL_EXPLICIT', 'SC_GLOBAL_IMPLICIT', 'SC_LOCAL', 'SC_UNKNOWN',
> '__builtins__', '__doc__', '__file__', '__name__', '__package__']
where the originally mis-spelled SC_GLOBAL_EXPLICT has changed to
SC_GLOBAL_EXPLICIT.
Can someone explain how this 'fix' is leaking out onto his machine? On all the
other machines I have access to I'm seeing something similar to this
