I don't think this is the case for most people in this scenario - at least in a general sense.
For a typical desktop editor sure, but for a mobile editor that goes through Google Drive I wouldn't expect it to have any access to any file in my Drive. And if it did, this could be trivially be used for many horrible things. Meaning, the "type" of data stored in Google Drive versus someone's Documents folder is very different.
