What this does is create a unique private key for each machine and put the corresponding public key in the other machine's authorized_keys file. You have generated two public/private key pairs, one on each machine. Afterwards if you want, you can remove the public keys (booga_id_dsa.pub and ooga_id_dsa.pub) on both ooga and booga. You do that with the following command: rm -f booga_id_dsa.pub ooga_id_dsa.pub Execute the above command while in the ~/.ssh directory on both ooga and booga. I renamed the files from the default id_dsa.pub only to avoid confusion that there are now two public key files, one for ooga and one for booga.
