Seems the article is confusing the "trigger" of an event with its "root cause".
I like to give the example of the Concorde airplane crash [0] to exemplify the difference: the incident was triggered by debris on the runway (which caused the tires to explode, igniting the fuel tank above). But the root cause was the placement of fuel in proximity of inflatable tire materials.
