Sure. Those are overly simplistic categories, but a full discussion of type systems in programming languages would be out of scope for that post.

Shadowing is a different issue. Shadowing refers to two different variables (which happens to have the same name), so it's orthogonal to whether the same variable is allowed to hold values of different types at different times.
