This allows BCR to record calls prior to the device being initially unlocked after a reboot. In the BFU (before unlock state), recordings are temporarily stored in an internal device-protected storage directory. If the call completes before the initial unlock, then a migration service that automatically runs after unlock will move the files to the output directory. If the device is unlocked while the call is still ongoing, then the recording will be moved to the output directory at the end of the call.
There are some limitations, like not being able to look up contacts or the call log, but most of BCR's will basically work as expected.
