You're correct. That's because in the darkride , there's a video projection so with this 3-4-3-4 seats, you can sea the projection better (and ofcourse more). It's just like a cinema.
Intamin has made the new system for the lift. Before the boat come's to the lift, it falls 6 meters down with a drop, en then up to the chain, but if the boat wouldn't connect directly with the chain, it would fallback and you could have a whiplash (or something like that), that was the problem. So intamin made a brake at the excact point where the boat has to connect with the chain. When the boat drops at the first drop and runs to the chain, the brake will hold the boat until the boat is connect with the chain, so it can't fallback anymore (if the system works )
I hope you all understood what I said
