No, a hibernated machine is powered off, you're thinking of standby. Hibernation dumps a memory image to disk which is then loaded on next boot. As laptop standby power modes has gotten much better, and memory sizes bigger, hibernation seems to have fallen out of fashion. Parent seems to confuse two different kinds of boot. The one discussed in the article concerns itself with getting the OS loaded and beginning to execute that. Traditionally, this is where booting ends. But you OS still needs to do a lot of work, starting services, loading widgets and helpers and Bonzi Buddy etc. It's perhaps debatable if this can still be considered part of the boot process, since the OS is loaded and executing user space code, but it's certainly part of the startup process. I believe this is the process parent is referring to.
