Thx Xarax,
I have one more question. I got information from Luca:
Beware gifts from Luca!

The "bottom side twist" variation of falsely tied Hunter's bend is none other than #1425!
Do you agree with it? I see some similarity, but I'm not 100% sure. (I met bend #1425 a few days ago, and I'd like to know more about it. The bend is recommended by Dan and Luca.)
Yes, once it capsizes/transforms into the other's form.
One reason I'm happy to see Xarax vanished is that he
is like a demanding teacher assigning wayyyy too much
homework : all the time he is opening yet another door
into the knotting universe and inviting others to explore
--yet still there are only 24 hours in the day and 7 days
in the week and ... !
Darn you to Heck, X!

Looking at the image of X's you (re-)present, I see in
THIS structure a shape in the S.Parts I'd like to retain
(so, to prevent its "capsizing" into
#1425)
and thus mentally re-tie it so that after the S.Part
makes its U-turn it reaches to where the tail begins
its exit, and turns around in the opposite direction
to tuck out through the center --thus binding the
S.Parts in their current-in-this-form orientation.
This revised knot draws up like a round rock,
and I surmise that it will prove rock-solid strong:
because the S.Parts' curvature is not severe;
and there will be little
movement of parts
to generate friction & heat & chafe (from cyclic
loading). Moreover, I believe that the tails can
be cut off snug to the body, at which point they
are bound by
two overwraps --so, should
they somhow retreat beneath the first, the 2nd
will yet bind them (and these wraps receive the
heavy load --ameliorated by the U-turn-- of usage).
.:. It could conceivably supplant the
fisherman's knotfor some uses?
Xarax shows various things akin to what I describe,
in the aforecited thread, but so far as I could see
there all of them have the S.Parts passing by each
other straight and then turning, not crossing each
other as for the
squaREef which I preserve in the
above revision.
(Yes, it has taken only a 2nd Coming after TWO YEARS
for my eyes to be led into this X opening --from as one
can see, a so richly/multiply set of things in 2011.)
