I do not yet use Zope 2.9. Therefore, my answer is very hypothetical:

  In earlier versions, copying a catalog contained a bug:

    The catalogued objects were twice in the catalog.
    A first time because they have been copied with the catalog
    itself and a second time due to the "manage_afterAdd" call
    for the true object copy.

    Maybe, "OpenFlow" contains some code to avoid this
    catalog copying problem -- and maybe, the buggy behaviour
    was fixed in Zope itself. Then, the correcting actions
    of "OpenFlow" might do too much.
