To achieve a rate of climb of 7000 ft/min, then reduce it to 700 ft/min in the time allocated in BEA's note, requires a level of "gee" that brought the AoA very close to the "theoretical trigger value". A little bit of turbulence could have done the rest, which explains the intermittent nature of the first two s/w occurrences. Nothing 'bogus' about that.
