Yeah DiDio confirmed that this is still Bart Allen I think over SDCC. With the same relationship to Barry that he had before. We just don't know how this transpired this time. They're new timeline is really screwed up in my opinion...and no I haven't spent too much time or really any time trying to reconcile it or figure it out. Just my initial observation is that it is one of the most illogical comic book time line rationalizations ever.
