I second that opinion. I think it's just a way to get back to a working

AFAIK it's impossible with the Hasselblad 500 C/M. Once you've tripped
the mirror and body shutter, you have the fire the lens shutter and expose
the film.

Nope.
You just pop-off the film back, release and reset the camera, and you're
fine again.

But this is about an RB67.
