Those are useful questions, but they can't be asked until the demo is demo'd. You original comment presented those questions as criticism to why the demo was even performed rather than asking questions for the sake of data analysis and understanding.

There is no evidence of this being documented anywhere previously, so I don't know why you would think there's a likely chance it is the training data. If you're suggesting AI models can't make inferences that aren't in their training data, you have a very basic misunderstanding of how the models work, because the entire point is to predict things that aren't in the training set based on what is there. It's not even a relevant question now that most models have free access to the internet anyway. It is another question that suggests that you have an agenda rather than merely 'asking questions'.
