Ann,
Jeff is a good teacher, but he is even more dry than I am and that's saying something! While there are times that Anchor point comes in handy, like when you want the corner of a PiP to be in a specific place, or you want some fairly irregular rotation, it is generally easier to leave the anchor point alone. As you can see from the video, Jeff didn't touch it.
I didn't remember exactly how I taught the same subject in my Lynda.com tutorials all those years ago, so I dug out the DVD to watch it. Long and drawn out with a complete description of everything I knew at the time, but I did hit on an important point that Jeff missed completely. It was rather funny watching him suffer through finding the end points and handles of his curves. There is a very simple way to deal with that, which indicates that Jeff never watched my tutorials, or he watched them so long ago that he has forgotten. 
If you select the Motion effect and then poke out the eyeball on the track (and maybe all of the tracks below it) then you will be left with the bounding box and the keyframes with their handles. Easy to see.
Like this:
Once you have moved them around this way a bit, they are easier to see when you restore the visibility of all of the tracks.
I have to tell you, that DVD had a little dust on it. I don't think I have watched them since I reviewed them for Lynda.com to make sure the editors didn't miss anything, or cut anything important. It ws funny watching myself move all of the individual little windows around. Be grateful for the vastly improved user interface we use today.
