Floor jack is designed for vertical load, not so much sideways load...

I always have both the wheels chocked in the start, when the car was fully on the ground.
However, when the jack is maxed out, you're right, the car has rolled forward a few inches.
Maybe resetting the wheel chocks at the top of the jack travel will prevent the car from walking as the jack is now lowered
