It means that:
(1) I can map an inheritance hierarchy to a suitable relational model (using a choice of various data modelling strategies)
(2) I can have an association, or a query, which refers to a superclass, and Hibernate will instantiate and populate an instance of the correct subclass at runtime

Polymorphic persistence preserves pointer relationships (or morphology) among persisted objects, and also allows the restoring process to restore an object without prior knowledge of that object's type.
