Well, let me answer this, since it's about the Prohaska not Re-Threaded Bwl.!
"Double-bight" is a mis-leading name; a better name would connote re-tucking
the end and binding a leg of the eye. But I'll prefer "Prohaska Bowline".
For the ProBwl, tie a single bowline and orient it before you on a table, say,
such that the single, fully loaded part (the "standing part" (SPart)), runs
away from you, and crosses UNDER the first part it crosses. The loop/eye of
the knot has two legs: one of them leads into the nipping turn formed by
the SPart; the other leads through this nip and turns around the SPart (to
form the "collar") and comes back through the nip beside itself and is the
end. (E.g., the double bwl. recently referenced at a WWW site was in this
general orientation, SPart entering by crossing UNDER the collar.)
To extend this single bwl. into the Prohaska Bwl., take the end over the
SPart-side leg of the loop and back under that--i.e., wrap this leg--;
then run the end OVER the end-side leg of the loop in passing out through
the SPart's nip--the nip will now nip the end (again), and hold its grip
on the SPart-leg, which in turn helps keep the nip in place.
While this bowline doesn't draw up as snugly as the End-Bound Dbl.Bwl,
it seems to adequately secure the knot against loosening in climbing
situations (though it might fail the test of some vigorous shaking).

Because THEY are confused/inconsistent/conflicting. In a separate thread
about side-oriented rap. bends, with Jost reporting testing done by Edelrid,
we saw the amazing fact that the tester & knot-inventer failed to recognize
that the presented knot differed SIGNIFICANTLY from what had been advanced!
But that knot, too, got the "TFK" name (which I reiterated has already been
better attached to an extended grapevine bend (which is a "double" fisherman's
knot/bend)--e.g., by _On Rope_, 1st ed.).

Ah, you might be right on this, in which case what I previously described
is an alternative method of "re-threading", which offers similar redundancy.
