That means that, by necessity, the New 52 was just the Pre-FP universe minus those 10 years and/or with the differences Manhattan caused.
The missing time led the timeline to adapt to those missing events. It like a domino or a ripple effect: you change one event, then that changes everything that relied on that event happening. So, because Manhattan killed off Alan Scott, then there was never a JSA and Courtney Whitmore, despite being Stargirl, was never a member of the modern-day JSA. Similarly, because Manhattan plucked out the Death of Superman saga (at least before Superman Reborn put it back), John Henry Irons aka Steel had to "re-meet" Superman in a way different than how they'd met before Flashpoint. Also, because Manhattan stole the original founding of the JLA, the JLA formed for the "first" time with Cyborg as a member instead of Martian Manhunter (though, now Rebirth may have put that back too).
So, yeah, there are differences, but those differences were caused by Manhattan, as Doomsday Clock has made clear.
