What happens is the victim will stagger back,
which will put them way out of place for the fatality.
As you can see, everything will work, just the victim and
the clamp will be no where near each other.
Huh huh huh. Splat.
You can do this with his other fatality too. Not that great though.
They still end up getting burned properly.
The little bit of smoke you see the the remains of the missile that
knocked the victim back.
