I also agree that the post showed no proof against rybka but I can see a
similiarity in the score and the pv.

13.01  0:22  +0.11  1.h4 h5 2.Rh3 Rh6 3.Rg3 Kf8 4.Rg5 Kg8 5.d4 Rb6 (2.430.131)
14/27  0:18  +0.11  1.h4 h5 2.Rh3 Rh6 3.Rg3 Kf8 4.Rg5 Kg8 5.d4 Rb6 6.b3 Rd6
7.Rd1 Rc6 (8.658.221) 460

Note that usually with clones you can see similiarity in early iterations and
not only in late iterations.

If this is the only evidence then of course it proves nothing.
