Probably because he noticed it was "plastic" and figured it was weak. Infact its a dense composite that is difficult to crack, and the design of the manifold gaskets being rubber and tall in structure prevents warping of the manifold from overtorquing on a flat surface(like the tgv to head gasket). The temperature fluctuations can change the characteristics of the composite so it needs a cushiony gasket for expansion and contraction. (much why the torque specs on maniold 10mm bolts are only 6ftlbs)
