@:-) As usual,
flyastrojets has the right answer.
The only flights where they checked me through, I didn't fly the identical route both ways. They probably built something into Sabre to recognize round trip vs. multi-city itineraries. If the computer doesn't believe you're on a 'round trip', they're allowed to check you in on all legs. Now it all makes sense.
