Maybe I don't know because I don't have a PS4, but aren't all operating systems like this? It's an optimization, holding some writes in RAM rather than immediately going to disk. The software needs to know you're powering off so that it can flush those first. You can probably configure some OS's to disable this (so that if it looks idle you could pull the plug), but it seems like a fine choice for a PS4 that rarely needs to be powered off.
