node type inheritance

In the JCR 2.0 specification, one of the built in node types appears
to inherit from a mixin type.

To be specific:

[nt:hierarchyNode] > mix:created abstract

Doesn't this mean that hierachyNode, a primary node type, uses a mixin
type as a it's superclass?  In other words, it doesn't have nt:base in
it's ancestor hierarchy?  And that's fine?

It isn't necessary to explicitly declare nt:base. It's implicit. As Alex 
said in a different thread, it is analogous to Object in Java.
