Flavio,
If you need to re track a shot every time you make an edit it's not the way to go. You are wasting time. It's ok that for a Flame, After effects, Smoke. The main reason we use a NLE is to edit, so if you loose what you already has done every time you edit, something is wrong.
Of course Apple is doing marketing, but not only marketing, the had done a very powerful software too.
Adobe and Avid does the same with the "one time offer" because they are going to charge you a lot with every upgrade later.
I think the intention of the videos is to show things to people are saying FCPX is not good without ever trying it (since it's a new way of thinking, you have to learn it. It's not enough to launch the software and doing some clicks with the mouse to decide).
