"The prohibited practice is commonly referred to as “back-to-back ticketing.” Flight coupons across tickets are used in an order other than that in which they were issued. Ultimately, it results in a wrongful effort to obtain a discount to which the customer is not entitled."

Wrongful? Get outta here! Gaming the system (legally, I might add) is no more wrongful than coming up with all these restrictions to try to wring more money out of customers.

With attitudes like this, no wonder the airlines like WN and AirTran are having a field day.
