That's the thing. Deadheading pilots are not off duty. A duty segment for a pilot can include, flying (as pilot) from LA to Dallas, deadheading to Chicago, flying to NY, then deadheading to Miami and finally flying back to LA. Not a very efficient use of the pilot's time, but still possible and they're paid by the airline for the whole thing and are on duty.
