Why do you do rm -rf git directory then extract tar archive to reset?

I'm not sure I understand your question. Are you asking why we have to
do a reset, or why we'd use rm + tar? The rm + tar restores the former
state reliably, so we can be sure it is correct. It's also independent
of the storage format details.
