Thanks for clarifying this, davidfor. I have just checked this with the novella I purchased from the Kobo website and it certainly loaded automatically on my Android Kobo app, with the bookmark in the last place I'd read on the Glo.
So it definitely is a "kepub" if purchased from the Kobo website, and hence my review is accurate.
I'll update the wording in the review to confirm this, later in the week when I do the next update.
