YMD is Sweden or Hungary. MDY is US and pre-1960s UK. YDM is Latvia. DYM and MYD are up for grabs.
Where do you get that from? Is this a confusion with dates spoken or written out in full as "March the 9th, 2023"? We're talking numeric form here, "090323" in the specific example, and I don't think the UK has ever used MDY for numeric forms.
I guess the confusing part is mostly because of an international audience. If everyone used MDY it would feel less weird. Still sorts completely wrong.
