One of the linked videos shows them getting under way and yes, they all appear to be identical tractors and they all shift at the same time. Maybe they have a cox on the radio who shouts commands: "Prepare to upshift. Shift 1 Lo, 1 Hi. Shift now, now, now." They probably undergo training to all use the same shift technique and timing.
