Doc error in OrderBook Tutorial

Question

At the end of the chapter for fault handling it says in the summary:
Reviewed the credit rating results returned from the Credit Rating service to the
client. The invalid social security card number that you entered invoked the fault
handling and exception management capabilities that you designed. A bad credit
history message was returned to the client. The BPEL process was terminated
before the Rapid Distributors and Select Manufacturing services were invoked.
The process continues successfully, just with a zero credit rating, since nothing is added to end the process. maybe that will happen in a follow-on chapter.. not there yet.
