It makes even less sense considering the synopsis for volume 3 seems to indicate things taking place back in volume 1's setting again.
From what I can gather from the comments on the wiki,it seems that Volume 1, which the anime apparently covered, was a dream reality created by Haruhiko and Volume 2 is the real world. Volume 3 involves Haruhiko going back in time to fix things and save all his friends who died in volume 2, basically turning the series into Steins;Gate.
Or something like that. Some comments are claiming that nothing in the anime has anything to do with the actual LNs itself. It's a mess.
