If you sent an account to his public key he should get it. He may just need to click the box to view his accounts. If you sent it to one of your keys then you would get the account back. As far as I know, you send accounts and coins separate. So only one or the other at a time. If you sent an account with coins in it then you may have sent him all the coins in that account. I can not be sure though what you did, as I can not quite understand exactly what you are saying that you did.
