That is because those machines are made in a way to mix the 'perfect' ratio of water + syrup. They take in account the ice as well. If the cup is 0.5l, it plans to be 0.4l of liquid + 0.1l of ice (random values), so if you chose no ice, you get 0.4l since that is the 'perfect' ratio. (And probably what they advertise ie '0.4l coke = 1 euro' or whatever, they just give a 0.5l cup to account for ice)
