Player View vs. NPC Fog of War

I noticed that, when I use Control-L to switch to the view of one of my player's tokens, significantly more of the map is visible to me than to the player. It appears that sections of the map in which NPCs are standing are visible when I am in player view mode, even though no details or creature/NPCs are visible. Below are screen shots of my GM-while-in-player-view vs. a screen shot grabbed by one of my players. Shouldn't entering player view mode also disable the fog of war reveal from GM owned NPCs?  vs. 

I believe the Advanced Fog of War "map" is player-specific, or rather log-in-specific. Not token or character specific. But I've been wrong before. :)

That is why I was thinking this is a bug, since it essentially breaks the Ctrl-L feature in the GM's toolkit.

Yeah, there's never been a persistent effect like this before. The option would be to save layer information for every token on the board within each instance. As I understand it.
