To be very honest, the guy sounds a lot like "brokenchair". It's not something that regularly happen that you get to know "a guy's" email with so much detail and still being able to remember it after 4 years. And if I presume, this "guy" we are talking about here is your friend then I must say you are not a very good friend, you introduced your friend as "a guy". As for your problem, I believe the guy need to go keep digging with blockchain.info. 12words always refers to blockchain.info as far as my knowledge.
