The only relevant pollees are people who would bid 3♣. If, surprise surprise, the TD can't find any such people all he can do is place himself in the mind of the 3♣ bidder and ask himself, "If I'm the sort of hcp-hound who would bid 3♣ with this hand, would I give any contemplation to passing 3♠?"
I still think this is wrong. The TD can place himself in the mind of the 3♣ bidder and ask himself, "If I'm the sort of slam exploring person that would rather bid 3♣ and explore slam only if partner bids 4♠, what bids would I consider when partner bids 3♠". There are lots of places where people make what looks like a game try with game forcing, slam trying hands. And then bid on when partner doesn't accept the game (hidden slam) try.
FWIW I may be a peer of this person if you asked me as playing this system I'd consider bids of 4♠, 4♦, and 3♣[always bidding to 4♠] and I'm not sure which of the 3 I'd pick.
