That's what I get from the report, that the TL was advanced forward of the FLX/MCT Detent, but it does not say it reached the TOGA. Therefore the mode never changed and it continued to follow the ILS, then all sorts of things happened in a flurry to recover the situation before terra-firma was involved. Nothing to do with SOP more to do with not confirming FMA change and when it didn't do what it was supposed to the startle effect crept in.
