You can ignore the extra text reference in the guide. That's just a quirk of mobi_unpack as far as I know. And even if it's not ... well then Kindlegen is introducing it and you can't do much about it anyway. All evidence points to this being a MOBI vs KF8 issue with regard to the handling of the "Start Reading" feature on the latest K4 firmware.
For what it's worth. I've never used anything other than 'title="Start" type="text"' or 'title="Text" type="text"' to mark my desired Start Reading point when using Kindlegen. But I don't have a K4 device to check it on. Also make sure you download the very latest version of the Kindlegen/Previewer (v2.5.1).
