I keep my RTH altitude at a max of 120M or 400'. I have heard stories of people crashing their mavic's using RTH, even with an altitude of 80M. If your Home point has an elevation of say 1,000' and you fly your drone over an elevation of 1,200', with tree height (~60-100') you would need minimum clearance of about 300' to return home without any issues.
So in layman's terms, I think the mavic pro sets a zero point where every you are standing and doesn't take in account other topographic elevations. This could be dangerous to those who fly around hilly areas with a RTH set low. So this is why I set my RTH to a max altitude of 400'.
