Not necessarily. Class variables could be defined differently from global variables. If a class variable were defined in the natural way, as an instance variable for the class instance described by the metaclass, then class variables would be inherited in the same way that instance variables are. A subclass object would have its own copy of its superclass's variables, just like a subclass instance object has its own copy of its superclass instance's variables.
