This obviously means if the threaded inserts/HeliClips rotate when they shouldn't, but I'm not sure that "must not rotate"/"rotating threaded inserts" quite hits the nail on the head.

Reference information: Locking Torque — The resistance to rotation. A measure
of the performance of the self-locking device. Does not
include the torque necessary to induce or remove any
axial load in the fastener.
8. Torsional resistance to turning (prevailing “on” torque)
is greatest at the initial installation of the self-locking component
with the mating thread form.
HeliCoil Locking Insert has a high reusable factor permitting frequent removal and reassembly of bolt without appreciable loss of torque. It has positive self-locking torque, complying with MIL-I-8846 & MIL-N-25027. http://www.helicoil.in/helicoil.htm
locking element - A device employed to restrict rotation of a threaded member while operating in adverse environments, such as vibration and temperature. The nut-locking element provides prevailing locking torque to the mating screw.
