ELI5: Why is it that a building with the AC set to 70 degrees on "cool" mode is colder than a building set to 70 degrees on "warm" mode? Shouldn't they be the same temperature?

Upper and lower boundaries. Cooling to 70 activates cold AC when temp goes ABOVE 70. Warming to 70 only activates heat AC if temp goes BELOW 70. If the building is above 70 then heat AC will never turn on because it's waiting for building temp to drop below 70.
