Yes, two different scenarios, but he both requested them. In 4 the jpdl is not only persisted as lob, al implementing classes are instantiated and that (java) object graph is persisted and executed once a process instance is started. If you take a look at the internals of the PVM, you can see this happening. So in the end, jpdl is parsed into objects and persisted, just like directly persisting objects.
