Yeah, even via different perspective it still shows. I'm wondering if it has to do with the exercise file selecting multiple rigs:
This is my guess and a stab at an explanation. The motion path for the ball is showing both the up and down and they are not symmetrical. Look at the values for frames 14 and 16, 13 and 17, etc. not in the graph editor, but the values in the 3d viewport in the transform position, they are probably slightly different. If you want them exactly the same play with the angle of the handles in frame 15. hope this helped.

ggrayblack83 The reason for it showing double is that the up and down are not the same.
It looks like you have a different amount of frames on the way up as the way down.
If you are starting on frame 01 and the middle is frame 15, then the end should be 14 frames later. (ie - frame 29).
But the keyframe is on f30.
This will cause the timing and spacing to be different, and hence the double dots on the motion paths.
Thank you both for your help, just tried creating an animation with a simple setup and the motion path still look same. I dont know how big of a problem it is, or if its a setting within Blender that I need to change, its just odd. ttanya, Yeah I tried messing with it in the graph editor, no change there either. I'll keep digging, have either of you experience this?

Wayne already explained it and it is a problem. It's not a Blender Setting, it's a mistake you make. The only thing that's odd about this, is the number of Frames you use. From frame 1 to frame 30 is 29 Frames and the middle of that would be 15½, not Frame 15, like you have.
If you mirror your Graph Editor and overlay it on top of the original, you can see the asymmetry:
The highest points should be on Frame 1 and 29, when the lowest point (ground) is hit on Frame 15. Animation is hard...(and to make it even harder, it also involves some math).

Just move the keyframe you have on frame 30 to frame 29.
Then it will be symmetrical.
At the moment you have 14 frames on the way down and 15 frames on the way up.
