I'm not sure where you think a passed hand by partner is going to give you a reverse to show a 4H/4S hand - but that would be the bid if it went: N:P E:P S:1D W:P N:(already passed, less than 12 points here) 1H E:P S:2NT (or 2S) (Reverse showing 18+ HCP) W:P N:3S (in an opening sequence, unpassed this is a 13+ responder hand, already denied having 13+ points) But hey, if ya'll swear up and down ya'll wouldn't be pissed at partner using a responder reverse with 7 HCP, let that system work for you - I've been yelled at WAY too many times for doing exactly that by too many very high ranked players.
