There's one thing to take into consideration though, if I remember this correctly:
When this "early draft" was released, we already knew about Peter's parents having a role in the film, about Dr. Connors having a large role with an audition for Billy as well. We had a picture of a zoo or something as a hint of the villain (which was obvious that it was Lizard). We knew about Peter being in high school. We knew about Capt. Stacy and Gwen. I think we even had a picture of Gwen and officers at the funeral back then.
This overview of an "early draft" could easily be something fan made, based on all the info we already had back then. There were already rumours of a "Van Adder" as well, who turned out to be Dr. Ratha. Whether that was a false rumour or Webb changed the name of the character is unknown.
