As I understand it, this patent claims to make for improvements in the transition from using one turbocharger to using both.

Not sure - the leaders and flow-annotations aren't very clear to me (A/C hydraulics and air flow are apparently not treated similarly in schematics).
It's possible to bypass the first turbocharger (the right one in the schematics) but when it's used, exhaust gases from all 6 cylinders first go to this one and only then to the other turbo.
