No, from version 9d, this is not the case anymore. Thats why I explained it in the way I did. The new rules are:
Copy Snapshot to Clipboard and Save Snapshot to File now deinterlace interlaced images and operate at Best (Full) resolution if the Video Preview is set to (Auto) size and Good quality if set to Draft or Preview.
So you can leave the preview settings to AUTO
