I thought that was weird too and my first thought was that it was a bug.
The I thought that maybe it was using the fact that an object in Python 
normally evaluates to True so maybe the code tests for True and if True 
tries to determine the type and perform some operation.

If that's what its doing I don't like it and think it's a bad design but 
it is feasible.

OTOH it may still just be a bug! :-)
