Well that's for us US wackos... If you're talking Europe, it's day/month/year rather than month/day/year. It's kinda like how the US uses Fahrenheit and feet while the rest of the world mostly uses Celsius and meters.
tl:dr: US is weird compared to the rest of the world
The post was about the date being the same forwards and backward, making dd/mm/yyyy the only correct format for this occasion. Your input about the format is as you said, "invalid" and also irrelevant.
