Your point is that the penthouse collapse disproves the assertion that in controlled demolition all supports are cut simultaneously. But that isn't the way it works. Most importantly, the central support columns ARE taken out early because they are the strongest and so that the rest of the building will collapse inwards and not keel over on neighboring buildings and such.
Second, there's probably no such thing as a perfect controlled demolition. Some charges are set off prematurely, while others are duds. That leaves some columns that aren't cut by explosives -- but they aren't by themselves strong enough to support the weight of the building, so they collapse anyway.
The problem, then, is that the "context" you appeal to is simply not applicable. The actual context -- the way controlled demolitions are actually carried out -- is obviously the blueprint for what occurred.
