In some cases there are suspicious values that aren't necessarily incorrect. The person writing the code might think: "I don't expect this value but it won't cause an exception in the way a null reference will". You may want to catch these in development and if they show up, you investigate and there is no actual problem with the value then you can update the assertion to more accurately reflect the data.
