This is frankly the cal developers being cute. Nothing requires this and the proleptic Gregorian calendar would have made more sense.

All in the name of a more simple calendar

Yeah and which calender? Gregorian I assume? Hard to know for sure!

It seems the algorithm would be better optimized for humans if January and February were always considered to be the last two months of the previous year. We're already used to doing this when working out birth years for Horoscopes and the Chinese calendar. Then we wouldn't need to memorize different dates for Doomsday in Jan and Feb, and instead remember Jan 2, Feb 6, etc.
