I don't think it's the same thing as From The Ashes. That pretty clearly was a shameless cash grab. This seems more like a scenario where it would make less for the ending not to be affected in some fashion. We're told we'll learn something about the Reapers' origins in the DLC; at the end of the game we meet the entity that created the Reapers. Having the former not make any changes to the latter would seem very odd.
