The Home Point is the reference, and the RTH height is relative to that point. So if you fly down into valley then you will see the altitude as a negative value (i.e. -200ft or whatever). If your RTH height were 100ft then the aircraft would rise from valley floor until it were 100ft above home point before returning. And yes you can fly over a cliff and it will stay at current height
The follow me requres your display device to have a good GPS signal.
My advice for the display device is get the best you can afford
