The new assignments can be helpful even if they don't cover downstream branches but you know the context. Like I got a new match I was excited about, but he was placed upstream of my main branch. And the reason for this placement seems to be that he belongs to the sister branch of my main branch, which being not covered by the FF assignments. So basically all people placed upstream of my main branch are highly likely to belong to this sister branch which got no assignment of its own. They are all out for me, since they can't be close, not even within the last 3.000 years.
Since a large portion of my matches belongs to this siblilng branch, it helps to sort all those not that closely related matches out. That's something I guess.
