The Square Enix account is just an account where you registered yourself pretty much. You link your serials from games and whatever to this. A service account could be called your subscription I guess. In some cases some people have multiple subscriptions and end up with multiple service accounts under the same SE account. Keeps you from having to remember multiple logins.

See this is where it gets tricky on if it would work or not for you because it depends what you did.

If you linked your ps3 to your SE account but created a NEW service account you could use them both at the same time paying the sub on 2 service accounts. You would not have access to your pc's characters on ps3 though. But if you linked it to an existing service account in order to play the same character on both pc and ps3 then yea you need another box.

The whole playing on a different data center work around someone mentioned could get plugged at any time so yeah.
