Not quite. By not returning to the point of origin, or another place covered by the rules, you are in breach of the contract, and if found subject to the repricing of the ticket on a point to point basis, for all the segments, a sum just shy of the price of a Ferrari. Some posters claim to do it all the time and be just fine, others are not willing to run the risk and don't even try. I belong to the second group.
