I’ve not seen the TR but if is below 100ft it will be something to do with the landing aspect of the flight control software. The A321neo from my understanding doesn’t have flare law compared to a CEO, its been replaced with something more akin to direct law where the sidestick input is proportional to output during that flight phase.
Interesting - kind of reverse of what Boeing is going through. If I read your post correctly, the potential exists for taking automation out at a critical phase of flight and putting the crew into 'more akin to direct law'.
