The jailbreak is stored in /var/local which isn't touched by updated (because it basically has user-specific data, not OS data
) and is restored on every boot when the Kindle startup scripts source /var/local/system/fixup. That is how it survives firmware updates.
They surprised everybody when they made the Kindle actually use a root account -- the jailbreak was still there, but useless without a way to elevate to root. That's where "gandalf" comes in, our friendly neighborhood passwordless su binary.
Now, the jailbreak also sources an emergency.sh file if present in the userstore, although I am not sure
exactly how Amazon could one-up the switch-to-root move.
Of course, they still might wipe /var/local but there are reasons to think they won't go that far.

As knc1 said, every update since the KT 5.3 days has been a full system image. There are still some partitions of consequence that don't get overwritten though.
