My interpretation is that in a significant collision, this safety disconnect on the positive terminal of the 12V battery interrupts the +12V power to the high voltage system. Without the +12V power, the high voltage system immediately shuts down.

If the high voltage system has been disabled due to a collision, 12V accessories might continue to function but you would not be able to drive the car and would almost certain have error messages displayed.

They do work off the 12V battery, but power to the 12V system isn't interrupted by the safety disconnect on the positive terminal of the 12V battery, so even if this disconnect has tripped, 12V accessories would continue to function.

I turn that orange switch off before I disconnect the 12V battery's negative cable when preparing our i3 for storage. This ensures that the high voltage system isn't unexpectedly shut down when the 12V battery is disconnected. This orange switch isn't part of the collision safety system.
I'm pretty certain that a safety box in the battery pack compartment can disconnect the battery pack in the event of a significant collision requiring the battery pack to be lowered, disassembled, and checked for damage. This safety box must be replaced if it has tripped.
