The drip shield may not technically "feed" the atty but if you over drip and it comes out the side of the atty into the shield, you can vape the atty and then when it needs dripping again, you can give a dry pull to suck the juice back through the hole in the atty. So for me, it does kinda act like a feeder. maybe. sorta. Not saying you can really over drip and flood the atty, but it does catch what comes out and after awhile, enough has collected to suck back in.. sorta like a freebie LOL
