To what do you attribute this? I find this interesting indeed.

I haven't the foggiest.
Perhaps there is no standardized training program for the tour guides. I seem to recall, although it is a little hazy, that the tour guide mentioned that being a tour guide was not her full time job; rather, she was intern for the Court and part of her job was giving tours. If this was the case, it might make sense that there isn't a set program for these people--which might lead to slightly different versions of the tour from time to time.
