I believe they were basically using this to cast a wider net before privately inviting more candidates to trial. I heard that Martha Long (principal of Oregon Symphony) was offered a trial from the audition. Not sure how many others they plan to have out.
I think just that other reports have stated Martha Long is not one of the 3 remaining. SFS does have a habit of inviting candidates directly to orchestra round (as you suggest), but it sounds like perhaps that is not the case here? Additional clarification needed
