Interesting... But THEY constantly conflate the curtain wall with the structure when speaking of the final collapse. If the curtain wall falls "at free fall" it means (to them) the structure did too.
The difference there is that the curtain wall could not free fall without the structure doing it first.
In the case of bulging the curtain wall would do so independent of the structure because it is bowing outward where it isn't attached to the structure with its ends constrained by the structure.
