There are two issues here - attacking for defense and consuming for
food.  If the only goal was defense, then a single bite or sting might
be effective - you are just trying to deter the opponent from doing what
he is doing.  Stripping a person to the bone is resource gathering - it
is far more than is required to deter someone.

This type of behavior might be reflex - that these insects automatically
swarm and collect as much food as possible when it is available.  If
that food becomes available during a defense maneuver, so much the
better for the hive since less energy is required to transport the food
home.

Plus, the orignal report said "millions" of them - if you had a million
needles and a needle gun you could probably "eat the flesh" off
someone's bones.  So even a single bite per insect would lead to the
effect that all their flesh was simply shredded off, not consumed.
