BPMN21 — Travel Booking Example

On page 27 of the above document there is an explanation of a Travel Booking process model.

In the 7th paragraph, there is a statement which says "If an error arises during the booking activities, the flight and hotel room reservations are reversed and the Client record is updated. The booking is tried again as long as the booking retry limited is not exceeded."

I believe that part of this statement may be incorrect as the client record is only updated if there is an error in the payment activity which is outside of the subprocess.

Could you please clarify?
