Answer Posted / rvg
if the three phase load is unbalanced, there will be a
voltage between the common point (star system) and earthed
ground( system ground), known as Neutral shift voltage. So
if you are short circuiting these, there will be a current.
Ir+Iy+Ib=Io not Zero for unbalanced loads.

Is a contactor (or master relay) required between incoming lines and a VFD? The question goes to safety. If a contactor were used before the VFD and an e-stop engaged then the motor will coast to a stop (i.e. VFD loses power) instead of stopping much faster if the VFD braking fucntion were used. It would make more sense to keep power on the VFD.
