What exactly does 'powercfg -h on|off' do?

My understanding is that it's supposed to enable/disable hibernation. But it doesn't seem to do anything to the settings of any power scheme. I would expect it to change some of the hibernation settings in the active power scheme.

My system has four power schemes. I used 'powercfg -l' to get their guids and dumped their settings out with 'powercfg -query <guid>'. I did this after doing 'powercfg -h off' and again after doing 'powercfg -h on'. Then I compared the output with 'comp' and they were identical.

So what is it actually doing if it the changes it makes don't show up in a power scheme?
