I am not sure how PFS should help against such unwanted decryption. Please, can you explain?

The attack is based on inserting old ciphertext into a new message. With PFS, the key would have changed.

That means, you can't read an old encrypted message a second time. Right?

You actually have to re-encrypt for storage, yes.
