Yes, you are close, but

The difference here is the kind of information being used. Quotes from people, that is direct witness claims differs from information presented based on analysis and data. You can look this up, if you like, or take my word for it.
Oops, what am I saying? You'll likely prefer to look it up, right?
Try this and let me know if you understand the difference involved here:
http://en.wikipedia.org/wiki/Expert_witness
Basically, we are relying on the expertise presented in the video that analyzes a particular piece of data: The Flight Path Study for Flight 175; and, in particular, the last 4min40sec of it.
That is what the video does. Or, more exactly, here is how the video describes its process and the data upon which it relies:
3--0:44-0:52--"Official story" of Flight 175 from National Security Archives is referenced as a data point.
4--0:52-0:59 Claims to use NTSB "Flight Path Study" that was based on "is this exercise or is this real world" data about which we do not know whether it is the one or the other.
5--1:00-1:28 References use of radar data from NTSB study in the reconstruction and explains the use of the flight path data points A to G.
See:

The video is, then, an exercise in providing an expert opinion.
So, if you want to attack the video, you have to do so by making the claim that it is wrong or that it isn't good enough for you for this reason, that reason or the other reason, backed up, of course, by some sort of solid sourcing of your claimed refutation.
all the best
