I think it’s much simpler than that. After Vizzini switches cups, they both raise their cups to drink. Watch closely; Vizzini waits for the Man in Black to start drinking first. MiB wouldn’t knowingly drink from the poisoned cup, but having sneakily switched them, that’s Vizzini’s clue that the cup he’s now holding is safe to drink from.
