can someone explain this freewheel remover?

A man in Kenya came up with this device. It seems to remove a
freewheel, but it doesn't appear to reach into the splines like you
would expect.

I don't understand his explanation. Can anyone speculate?

I have a vintage French made version, given to me long ago.
The big bolt on the outside deforms the freewheel body edge
enough to bind the freewheel which may then be spun off.
(I've never actually used it myself)

Would the device deform the body permanently, so as to trash it, or
spare it?

It was explained to me that you only need tighten enough to
make it not freewheel during removal. If you can imagine a
worn four speed freewheel with damaged notches, it seems a
reasonable approach. Alternate methods start with 'remove
axle'...

I'd guess the sprocket body is pushed outwards and acts like a strap
wrench around the cone. The deformation required is small and even if
there were permanent local deformoation (because of inadequate
hardening) it would likely be reduced by the unscrewing of the last
sprocket.

aaah I do that but with a cold chisel, 11 pound hammer, tubah4 blocks,
concrete wall and propane torch.
