This benefit is not a rescue benefit.  For example, if you are hanging from a cliff, with or without any medical conditions, it will not cover for a chopper or airplane to pick you up.
It will not take you from a non medical facility to a medical facility.  For example, if you are in a ravine and need to be rescued due to a medical or non medical need.  It will not do this.
Thus, this evacuation benefit is not about rescuing from a life/death or serious medical/non medical situation.
