Question about geocoding with “ArcGIS Online World Geocoding Service”

I have been teaching myself Geocoding in ArcGIS. I have a questions about how geocoding with “ArcGIS Online World Geocoding Service” works. I noticed that every time I use the online geocoding service, I get all of the addresses matched. This is the case even when geocoding the same addresses with a custom-made address locator produces several unmatched addresses. To look into this further, I created an address table with a few addresses purposely miss-spelled and a few missing street addresses altogether (with city name or zip code only). Once again, the custom-made address locator identified the errors I introduced but the online geocoding service still shows them to be a match but in this case to the city or zip code. I also noticed that the online service does not allow you to adjust geocoding options like spelling sensitivity. The bottom line is, I am concerned that I will not be able to identify addresses that were not matched to their street location when using the online service like if I was working with a custom-made address locator. Does anyone know why the online service does not identify unmatched addresses?
