Well, your question was " what's better than a completely separate air source?" In my opinion - it's worse than a completley redundant air source. For one reason - it gives no protection whatsoever for a neck o ring blowing. Financially - you have to buy a new valve. You have to buy another first stage. So for the price difference you have the illusion of redundancy without actually having it. For a couple of hundred quid? Not for me.
Is it better than diving a standard single - yes; but don't kid yourself you're getting a redundancy benefit.
