And how does a factory reset clean up all these keys as it never formats the whole system AFAIK. Can anyone explain me regarding this?

Correct, it does not.
But it does wipe the backup copies and installation scripting in the "hidden" user storage area, /var/local
Amazon uses a full image of the system partition for their update.
"That" is what over-writes the keys.
With the order of:
You are back to Amazon 'stock' state.
With the order of:
(An image update ends with a system reboot, which runs the automatic re-install code for the keys (all of them) ).
That is, the jailbreak and its supporting files makes the jailbreak "viral".
You don't install a jailbreak to a Kindle, you infect the Kindle with the jailbreak.
So once the system is back up, where you can press "Reset" the keys have already been restored.
All the above action order does is wipe everything EXCEPT the keys. So this order of actions can be recovered from.
So the simplest advice to give anyone other than a system developer is:
"Do not ever touch 'Reset', never, ever. "
