The situation is if the a group of the faithful that is too small to support such an effort in a parish request it, or if there are no clergy capable of performing it in a parish, they may approach the bishop (Art 7). The bishop is encouraged, in his solicitude, to create a personal parish (Art 10) for the purpose of providing the Sacraments in the old form (Also see UE Art 17 §2 and Art 23).
Yes, that’s it. Note it says the bishop is “encouraged”, not expected to do so.
