The Manila Leg screams replacement because the tasks are all very simple, easy things that can get staged at the last minute. Obviously, replacement Legs are still planned out from the start of course.
But if they wanted to visit the Philippines again, I would like to think that they'd at least leave Metro Manila if they had a choice. It feels very much like a backup Leg like the Kuala Lumpur Leg from *shudder* TAR24. Though the tasks here are at least a little bit more cultural for the Philippines which the other four Legs in the country may have lacked.
I don't know if the huge jump from Manila to New Orleans also shows it's a replacement Leg because that's definitely not a simple series of flights.
