Yes, but you haven't shown any difference between a and b.
Did you try setting active slot in fastboot?

If this were mine I'd open it up and find the UART.
That will give you some information on bootup.

Which slot is active is part of the OEM code.
It is reflected in the GPT type GUIDs.
I can't say if the slot is driven by that or a secret bit somewhere.

It should be possible to write some code to swap the a and b.
But if you screwed things up it would just make life that much harder.
