If soviet control of eastern europe during the cold war ended at Berlin, how was it...?

If soviet control of eastern europe during the cold war ended at Berlin, how was it that Germany was controlled by Russia after WWII further west?

Simply, simply put; it didn't. It extended about, oh idk, 50-100km further west, East Berlin was actually an island of Eastern control in the middle of the Soviets, that's why when they blocked the city we didn't just drive supplies in from the east, they owned that land too, so that's why we had to airlift supplies.

Google "Berlin Airlift" for the information and a map to show that Berlin is indeed inside the former Eastern Germany.

The American forces were ordered to stop their advance into Germany and allow the Russians to bypass Berlin and head into western Germany because the border had been agreed to by a dying FDR at the Yalta conference. Initially the Russians allowed the US to supply Berlin overland. Later when they tried to take the city through siege and stopped the convoys from getting through the US and Britain started the air supply system. The first time air supply of this magnitude had ever been tried and they were successful.
