Interesting.

It looks like the control stick is rigged so that it
does double duty as a mixer, is that correct?

I would think you'd have to use mechanical mixing to get elevon
control on one stick. It would be very interesting to see a schematic
diagram of the control cables on that ship. That's a very interesting
old bird.

'Elevon' control mixers aren't as complicated as that required for a 'V'
tail. From Peter Selinger's and Dr. Reimar Horten's book "Nurflugel"
describing the Ho-1 control system:

"The elevators were moved by pushrods, the ailerons by cables, all attached
to a conventional stick." "The pedals were linked to drag rudders near the
wing tips. They could be operated separately for directional control, or
together as spoilers, something that had not been introduced on other
sailplanes".

One can only imagine the self confidence of Bros Reimar and Walter Horten
who first flew the Ho-1, their first design, in 1933. They had no previous
work to draw on so they had to trust their instincts that it would indeed
fly.
