Eureka Seven: New Order is more than a simple recap with an alternate ending. As a prelude to the then upcomming Eureka Seven AO the episode's goal was to give both new and old viewers a recap of the previous serious with one major change in mind. The ending. You see Eureka Seven's ending was very different from its source material and while the ending is way happier than going forward I think Bones thought it relevant to realign the anime as they prepared to release the new series. Whether this helped Eueka Seven AO I cant say but never the less I can definately see from a story standpoint why it was done.

Both endings are great and the only differences are that one is a little more rewarding than the other while the other is way more emotonal. Never the less the episode did set expectations for how Eureka Seven AO.
