The lines above run in the test01's global namespace, not in the global 
namespace of the importing module.

Think of import as a function like

exec("test01 = load_module('test01')", globals())

Then it should be clear that the name 'test01' is put into globals(), if 
load_module() doesn't throw an exception. No sharing or nesting of 
namespaces takes place.
