Thanks for the link. At the end of the day, its all to do with the interpretation of "numbers" and how they correlate with your own situational awareness. Stuff up one side of the triangle and either of the other sides will get you.
Exactly what the flight path was that lead them to this situation, can only be guessed at. The "runway in sight" call 4 secs prior to the initial contact, would as you suggest, indicate they were not visual immediately before the call.
