Here is the discussion thread. We were talking about what possible alternatives to phosphorus are for alien biology. I see your point, but would point out that this article is discussing similarity among bodies within one solar system, which makes sense as we all condensed out of the same planetary disk. The other article is highlighting dissimilarity between solar systems due to location. The makeup of planetary disks seems to differ based on what kinds of stellar explosions contributed to them. This also makes sense. Now I am wondering if the answer to Fermi is that the universe is only just now becoming capable of making planets with enough elements for complex life?
