I'm not sure where I've heard the term first but I grew up in Italy and lived in Australia for 10 years, neither of the two has a large Mexican minority and so it might be that people are more likely to mix up these terms or use them incorrectly. I did not know the difference between "nachos" and "tortilla chips" and I was under the impression that they were synonyms until I've read your comment, thank you for your detailed explanation! Also I did not know that tortilla chips and corn chips were not the same thing, that process that you described is really interesting, Mexican cuisine in general is very interesting I think
