Seems to me the operator was trying to impress on the ATSB that the safest option, in this instance; was to land slightly off the runway rather then trying to conduct a go around in the high wind low vis situation. Outcome kinda of speaks for itself: nil aircraft damage, nil injuries, 1 busted runway light.
If the aircraft had gone around, while suffering wind induced controllability issues with those mountains either side in low vis, could've been catastrophic. I'm sure the LHI board would find that a lot less palatable.
