he has said that he used pgp in his emails with poitras and greenwald because he knew from personal experience that, properly implemented, nsa was unable to decrypt messages protected with it

Are you saying he didn't use Lavabit and Cryptocat?

He used PGP over Lavabit. So even though Lavabit was compromised, content of his emails is secure.
