No, the article is about kerning a typeface, not simply rendering existing kerns contained in font files. LaTeX does many things but auto-kerning is not one of them. It can only execute embedded kerning pairs (metric kerning) it can't infer its own (optical kerning).

Aha, thanks for that explanation, that was really useful and concise. I've learnt something new today, which is always good :)
