Model not deleted with shape?!

I have 2 shapes on my diagram. Each of these shapes has a model object assigned. These 2 models are linked:

MyModel model1 = MyShape1.ModelObject as MyModel;
MyModel model2 = MyShape2.ModelObject as MyModel;
model1.Container = model2;

After I delete MyShape2 using "Delete with Model" menu, model1.Container does not become null - it still refers to the model2 object; I proved this using hash code. Is this behavior by design?! And if yes - am I supposed to unlink models explicitly?

As the framework does not know anything about your model objects, their properties and their relationships, it cannot 'unlink' them by setting the 'Container' property to null.
