In mountainous terrain, you might come down on a steep slope and slide, or swing into a slope as you descend. The recent Arizona Cirrus seems to have been swinging, and ended inverted on what looks like level terrain.
The Arizona pull was over fairly level ground, was not in mountains or swinging but a fairly straightforward pull after engine failure.
As I understand it the pilot encouraged the chute to inflate on the ground to visually help SAR services who were having trouble locating him.
Eventually he was rescued and was about 1/2 a mile from the plane and the first responders insisted he was taken to hospital for some checks and reassured him they would stow or cut the chute, which did not happen and later a gust of wind caught it and flipped the aircraft over.
The chute once on the ground is a potential hazard in high winds but also being bright orange makes a great extra visual locater both in the sea and on ground for SAR.
