The key finding in the report was that the missile was fired from a specifically calculated area -- shown in red, in figure 62 -- that lay squarely within rebel-held territory. This by itself is quite damning for the pro-Russian side.
Whether the missile happened to have been fired from one of the 3 villages within that area, or from unincorporated territory is basically irrelevant to the report's main conclusions. And whether some CNN reporter, or his editor, may have fudged a bit on this basically irrelevant detail (shortening "fired from an area near village X" to "fired from village X"), even more so.
