If I'm tracking what you say correctly, all four collapse.  If you thread
a photon on a closed loop, it goes through all four wormhole ends, and
every wormhole on that path collapses.

If there were nothing else that could collapse a wormhole, perhaps so.
But I presume there are other things, such as trying to stuff too much
mass into one end, that could do the trick.

True, from an "explain why and how it works" point of view.
But in terms of "coming up with new mechanisms" point of view,
the prefered frame is more speculative. There are already some
reasons to suppose lightlike pathways must collapse.
