The difference is that in the #1 point he was talking about not simply implementing the features of a competitor. If you notice company B has feature X and therefore decide you must have it as well, you may be in trouble if it turns out feature X isn't useful and is hard to implement.
So, it's obvious that while Google wasn't the first search engine, they also weren't simply copying Altavista's feature list.
Google is a good example, in fact, because they followed #1, #3, #4, and quite possibly #2 (a search engine that doesn't suck? How novel!). There also might be doses of #5 sprinkled throughout Google's work.
