But seriously, it could be that they envision people removing the reader from the cover when reading (and putting the cover in a sunny place), so that the cover will charge while reading and that in turn will charge the reader once it's put back on.

Solar cells don't need go be in direct sunlight to work. Ordinary ambient light, even indoors, can generate a small ongoing current. A cover-sized reader probably won't keep a reader permanently charged under normal use but it can probably extend the time between charges by a decent fraction even in indoors-only use.
Of course, if you keep it in a drawer...
