If Confucius or Amina would be able to gain points for the legacy paths in the exploration age, they would create age progress for the militaristic legacy path - regardless of whether they‘ve been met or not. But the progress was at 0. It can be that they had less cities in the DL than required for the first progress (and no religion yet when the screens where shown). But to me it looks like DL civs don’t work well with the economic and militaristic path and will thus not create progress. Also, if they did „compete“ in generating progress points, the second age would be shorter than the first due to more players gaining points and accelerating the ending. That also doesn‘t sound right, somehow.
