You're all forgetting the very important fact that we can only see one side of this scene. On the other side there's a big path that all the sligs and glukkons use, and then walk around to the doors.
Like this -

*Big ass path on other side*
And yes, I know that image exceeds it's physical bounds (there's a transparent bit around it

)
Edit: What was I smoking when I said that last bit. Vectors, probably (in reference to
this thread)
To summarise, it made no scene (only the last bit, the rest was clear as day). Apologies
