The split is based on the assumption that the final front line of the Eastern Front, when the Whermacht and its remaining allies do their mostly successful stalemating last stand until the Anglo-Americans arrive, diasrm them, and keep their ground, would be essentially similar to the OTL one by end of 1944. At that time, the Eastern front divided Poland at the Vistula, Hungary at the Danube, and Yugoslavia at the Croatian border, more or less. Moreover, it is also assumed that Stalin, seeing his hopes of conquest in Central Europe evaporate, would act rather more swiftly, blatantly, and brutally to impose total Soviet control on the lands that the Red Army actually conquered (e.g. the Soviets broke the armistice with the Finns and occupy Finland, crush anti-Communist partisans in east Poland, support Communist insurgency in Greece against the British, etc.). Such jump-started Sovietization and the separate conditional surrender of the European Axis to the Western Allies would prompt both the WA and the Soviet occupation forces to maintain their positions, and it would quickly collapse any perspective of creating common governments for the divided countries, so that the military demarcation lines would quickly evolve into defacto borders of rival states. The same process would happen ITTL for Poland, Czechoslovakia, and Hungary, that IOTL happened to Korea (which instead becomes all Communist ITTL, whileas China too gets divided).
