My understanding seems to be:

iswitchb-buflist already contains all buffers needed although its order
can be modified by iswitchb-next/prev-match. That modified ordering info
is lost after iswitchb-make-buflist. There may be new matches appearing
due to buffer name changes but this is taken care of automatically by
iswitchb-exhibit.
