It couldn't.

  Pretty damn close though! I haven't seen an explanation of what the second figure is trying to show so I'm not sure about that one. (And also their assertion that no further explanation is necessary is clearly bullshit.)

    Its attempts at explaining both figures are totally wrong. Wrong side lengths, wrong assertion that the small triangles fit inside the large triangles, wrong relationship between the figures, complete misunderstanding of the second figure. The second figure is actually showing another arrangement of n²+2 small unit equilateral triangles covering an equilateral triangle of side length n+ε.
