That is not always accurate. It is relatively easy to configure an MTA to support Sender Rewriting Scheme, either for everything that is sent out or just things that don't originate from the system.
Thus a .forward is not guaranteed to fail SPF validation. In fact, I would expect SPF validation to succeed on servers that are configured with SRS.
