It looks as though you only created one key, and copied it's public
half to authorized_keys on both machines. The private half should be
on the originating machine, and the public half on the machine you're
connecting to, so you'll only be able to connect from the machine
where you executed those lines to the other.

To let it connect to you, you should repeat the equivalent of the
first two commands on it: generate a key pair there, and copy the
public half over.

The 2nd copy doesn't do anything useful unless you have the same
private key on both machines, and that's probably a bad idea.
