The devil is in the detail
Not a pilot just interested in aviation, but even I can work out that if I can drive my car at 10 mph into my bendable gate post and leave a massive dent, expecting something of the mass of an A320 to survive in large pieces having flown into an unbendable rock wall at over 300 mph shows a certain lack in the joined up thinking department. I also note the very carefully worded statement that rules out a 'classic' depressurization situation. I think 'classic' is the key word here and could speak volumes.
