The report seems to suggest that they were in Mode 4B:
Mode 4B
: When the landing gear is lowered, Mode 4B becomes active and the boundary decreases to 100ft when above 120 kts. As airspeed decreases below 120 kts the warning boundary decreases to 10 ft
at 80 kts. The landing gear was down at the time of the accident.
