I think any conversation of a “sequential” failure of “floors” is utterly pointless. We could apply Newton’s third law to such a scenario, but it would be irrelevant as the application is changed in a way not reflective of what occurred on 9/11.
How does the application of Newton's third law change exactly?
As interesting as this paper may be, it still does nothing to refute Bazant's limiting case. It is a comparison of apples and oranges.
