The popstate only contains a state when there is one. When it goes like this: initial page loaded new page loaded, with state added via pushState back button pressed then there is no state, because the initial page was loaded regularly, not with pushState.

You can easily confirm this by looking at the HTTP traffic monitor in browser’s web developer toolset (press F12 in Chrome/FireFox23+/IE9+ and check “Network” section). … Read more
