I'm not sure Bjo was ever aware of the graphic, but Greg Jein definitely was (he cites it in his article in that issue of T-Negative, although he incorrectly attributes it to "Space Seed"), and apparently he was doing some work on TOS (probably as a gofer, but I'm certainly open to correction there).
