Exactly, it's the same reason most date formats don't start with the year, even though it is the most significant of the numbers. If I write 12-8-2019, the 12 is the most important number for me, in speech I will usually refer to the date as "the 12th". In the same way, if I'm telling my address to someone, I'll just say the street address, since we can assume I live in the country we're in right now (which of course doesn't work on the internet, hence we specify additional information at the end).
