I've noticed this before but today was the first time I got a handle on it. I received a new kernel and did the appropriate update and reboot. Then I checked using apt-get to see if there were further updates, as there often are. What I got was an advice to run apt-get autoremove to clear off some now obsolete kernel version material.

Later on, the software-updater requested a reboot. What must have happened is the autoremove processing, having rebuilt the grub tables, set a reboot switch which was probably not really needed since there was no new kernel to pick up.

This isn't much of a problem, but it does indicate that some minor thought needs to be given as to whether there actually is a new kernel present and not just a fix-up of grub tables.

While this is a minor nuisance, I hope it is not a symptom of something worse in the future.
