Is it the battery life that is making you suspicious about the sleep?
If you have the correct settings on (to listen for a sleep cover), the Glo should go to sleep when the cover is closed, following the same command that is given when you slide the slider. So I don't think it's a different kind of sleep, no.
Good luck with splitting the book! I'd also check for (missing) chapter markers if I were you. Running a calibre convert should sort them out if there are any missing.
