Although he may have meant it in a sense that the entire attraction isn't walk through - personally I would class an attraction with a walking segment a walk through attraction (Hex or Sub-Terra).
As well as this, I noticed that there aren't any chest restrictions for the ride - possibly meaning there won't be a restraint or it will be minimal, something like a seatbelt perhaps?
It's very exciting, not long now!
