Perhaps there was not a problem with the final landing, but there seems to have been with the initial approach.
I saw something similar at Murcia, when a low G/A was made by an a/c lined up for 23R the RWY to the north of the terminal and still under conscruction. This was from a straight in VOR/visual. I can't remember if sun was a factor, but on a modern GPS/EFIS a/c I'm sure the Map would not have been lined up; and as the RWY was not open it surely could not have been in the FMC data base, thus the TK line must have shown an offset. In a non-GPS a/c this late minute Map X-check can not be made (unless on ILS), but in a GPS a/c it can be made from any approach.
However, the spacing between Rwy & Taxi way is so small that it would probably not be noticeable.
Shades of LGW & AGP many moons ago. Were there any confusing NOTAMS? and was the crew visual from far out, but not looking out?
