Moreover, if other players have completed that
same objective in previous turns, these players each score 3
points (this does not happen if the objective has been completed
during the same atelier phase).
What exactly does the bold text mean? Does it mean that you can only get the 3 VP bonus once during the same atelier phase even if multiple players complete the objective during this atelier phase? or is it there just as a clarification that you don't get the bonus if other players complete the same objective(as you just did) during the same atelier phase?
