    When the flash contains multiple programs then you want to be able to remap the interrupt table to the part of the flash that contains the currently running application.

    So if you use a boot loader and an application the the boot loader and application each have their own interrupt tables. The processor boots the boot loader and uses the default location for the interrupt table. When switching from boot loader to application you also remap the interrupt table to point to the table in the application binary.
