Yup, I noticed that too. However considering I seen the original(s), or at least close to it back in 96or97 the water trench wasn't in there then.
The sniping spot across the bunker had a one way wall too, I forgot how to build it, maybe a sprite masked wall. You couldn't see the opening from the lower ground area.
