No it does not. You just have not encounter a problem yet.
But I expect you will.

I must admit it never occurred to me derive the way you are
trying to do. Python's needs do not allow this to work.

If you read the template code for PythonClass and PythonExtension
you will see that both create a lot of static methods and data structures.

You cannot just derive in C++ and expect the Python glue to work,
except by accident.

As I said you need to organise your class's so that you turn the
leafs into Python objects.

Are you deriving for code reuse or relationships?
