Unless, they weren't flashbacks but results of traveling through a wormhole into an earlier period of time, altering the timeline as we knew it, and..,oh wait Abrams already did that.
That would be horrible if it was unless it resulted in George's version of the PT never existing and that the OUT, and the new trilogy being part of this altered timeline.
Would be redundant for JJ, LOL. Though Jar-Jar would die, so maybe it works out. ;)
