I voted "other" because it would appear that the intent was to only provide the faculties to hear Confession and as they are priests first who have attained the full measure of priesthood in the episcopacy, this would apply to them. However it doesn't appear to apply to the other functions and duties of the episcopacy. Most priests would argue that to be given the jurisdiction to hear Confession automatically infers full ordinary jurisdiction, but even then, it is not obvious to me that would also be true for a bishop. For instance, an auxiliary Bishop still needs to be supplied jurisdiction by the Ordinary and does not have the jurisdiction to operate as a Bishop just by virtue of his Consecration.
Methinks such an arrangement is probably unprecedented in church history, but it falls under the canons of church law and a true Pope is the final legislator and arbiter of Canon Law. Burgolio is much too vague by design on all important matters, except global warming, to finesse the terms of this boon he is providing to the SSPX.
But it does raise the question of whether the SSPX Bishops would be given a titular See if/when the Society is "regularized".
