Bob's X-T1 has a dual shutter, or two shutters if you prefer, Jim.

The e-shutter captures light scanning as an old TV set created an image - 
which leaves time for a fast movement to trigger the effect.
It is the one shutter that is used when shooting in silent mode. Hence my 
question.
The phenomenon may also happen when the e-shutter supersedes the mechanical 
one i.e. for speeds above 1/4000 if I remeber well.

The rest is chronophotography.
