The DRM tool shouldn't care about what's in the .kepub and so long as it's designed to decrypt .kepub, it will do so for ALL .kepubs including these.
Kobo's .kepub.epub files are simply renamed .zip files (exactly the same as a .epub file). You can open the file with your favourite unarchiver and look at the contents. The encryption is applied at the level of the files inside the archive and not on the archive itself.
