Whats the meaning of low kick or mid kick point

Hi guys would like to clarify the meaning for driver shafts when they mention low kick point or mid point. What's does that mean and in terms f swinging motion and follow thru, how does that affect striking the ball..

Definition: Kickpoint, also called flex point or bend point, is the point along a shaft's length at which it exhibits the greatest amount of bend when the tip is pulled down. Ball flight is affected by the location of the kickpoint, although to what extent is a subject of some contention. A general consensus is beginning to emerge that kickpoint has only a very modest effect on ball flight. A high kickpoint may help lower the trajectory of most golfer's shots; a low kickpoint may result in a slightly higher trajectory for most golfers.
Also Known As: Flex point, bend point

I am sure there are many here who can add more input to this.
