And since aeros are not a part of ATPL training, this crew may not have been familiar with negative g at all.

A negative G sensation can have this effect on pilots unfamiliar with aerobatics.
There have been few strange glider accidents where students nose dived theire plane after a rope failure during a winch launch. They are trained to push hard after a rope failure to regain airspeed to a nose down attitude.
But in some rare cases the students kept pushing into nearly vertical nose dives.
The negativ g sensation triggert a "Warning, something is wrong" and the reaction "Pushing is allways good" even increased the effect and the students pushed the stick forward even more.
