According to this reasoning Greg Jein didn't "know" either, as he never made a reference to this explicit line "Basic Specifications, Constitution Class Starship" in his original article which I recommend reading: http://www.trekplace.com/article10.html
I have strong doubts whether this line is even authentic (this is a script for an episode and not the writer's guide. I believe in real life it would have read "basic specifications of the Enterprise" as most people involved with the production, like Bob Justman, would have otherwise wondered "What the heck is a Constitution Class Starship?").
I'm not sure to what you're referring in your query ("whether this line is authentic"), but if it's to the "BASIC SPECIFICATIONS..." description in the script, I can assure you that it's transcribed correctly.
