I think you misunderstood. If you're dragging thumbnails onto a flash drive, it'll copy the source photos, not copies of the thumbnails. The terminal example is thumbnails or full photos since the files themselves can't be used by the terminal. You have to specify whether you want it to pull a location for the thumbnail or the full photo. In that instance, you wouldn't be using multiple files because there's no use case for a terminal where sequential files would be used without some kind of additional characters or arguments.
