There's nothing wrong with
end-on-end ticketing (which is probably what you did).
Back-to-back ticketing is verboten because it circumvents airline fare rules. For example, a back-to-back ticket may be used to circumvent a Saturday night stay requirement, a Saturday night stay usually being the difference between a cheaper fare offered to leisure travelers and a more expensive fare targeted at business travelers.
