The risk of not using the last leg of a xONEx is not the risk of using your miles. The risk is that the issuing carrier can theoretically come back to you and ask for the fare difference between the xONEx and separate tickets for the not completed RTW. No idea whether any airline has ever done that but in theory they could.
