How does the deployment on FE8 Final Chapter works?

Hello there, been a long time.
I want to know if someone knows how the FE8 Final Chapter Deployment works.

As far as I know, the game final chapter forces you to use the units you deployed for the 21 Chapter and those who survived are forced on to be deployed without a combat preparation on the chapter 21x.

How does that work ?

It uses a LOAD3 command.
