A lot of it is hedging and using lots words to avoid saying something that isn't true. That way, it looks a lot like text that contains meaningful information, even though it doesn't. The speaker can pass the scrutiny of an informed audience, because they are able to substitute their knowledge into the words, as if by pareidolia. It's the sort of 'diplomatic' language you see from politicians, lawyers, students writing essays, and any other moderately intelligent person who is put in a position where they will face consequences for not answering. Behind all the fluff, there is a very loud voice yelling "I DON'T KNOW."
