Agree, see smoke before the break - however have in mind physics - light travels fast than sound - you will always see the smoke before the hearing the gun

On slow-mo, there is no movement until after the gun flash/smoke. However, the movement comes so soon afterwards that it is likely that
a) it looked like a movement before the gun to the naked eye of the check starter, and
b) the decision to move, whether a deliberate attempt to guess the start or purely accidental, would have come before the gun.

If this occurred in a major amateur event, it is highly likely that the time period between the gun and movement as measured by pressure against the block plates would have registered as less than 0.100s and thus been judged a false start.

Either way, it has very little to do with Physics in this instance as the smoke/flash and movement are both visual indicators.
