It's just very unintuitive and it deviates from the popular and most accepted paradigm. I would think Google drive syncs your actual files, and that it would just choose Google Docs as its default editor.
Google Docs, however, does not provide "actual files" with substantive content for its native documents, you have to export them to other formats to have "actual files".
