There is a danger in chronic abuse resulting in upregulation. Mixing the two at once is no problem for the liver, which is also why patient information leaflets for paracetamol do not contain a warning to avoid alcohol, only about chronic alcohol abuse.
Your crappy source is vague in what consumption pattern constitutes a risk and actually cites a better source that supports the idea that acute alcohol consumption reduces paracetamol toxicity. https://www.biorxiv.org/content/10.1101/2020.07.07.191916v1....
That's a mathematical model, but this relationship between the two is what I was taught in medical school and it is still supported by the science. There's plenty of other sources, I just picked that one because your article cites it. Just search for "paracetamol ethanol" on Google Scholar.
