When i read those comments by Nina van Gorkom my impression from that is that one never comes to a point of really uprooting defilements unless Nibbana is experienced with magga citta. Only magga citta can do the uprooting. So, my impression is: one can weaken defilements and anusaya but not really uproot them when one has no direct experience of Nibbana. Experiencing Nibbana is a necessary condition to uproot then, and they will never arise again.
That is what i understand from those comments of Nina van Gorkom.
