I agree with this. There are fudge factors for a reason. Like you said, we do not know what their intensions were or their exact altitude (But to me it looks lower than 400).
If you are honestly trying to make your approach stable and at 1,000/500 feet but the flaps are still in motion, the gear is in transit, or your speed is still slowing to approach speed, you have to ask yourself if you have this thing under control and how much longer will it take to be stabilized. My rule is all configuration changes definitely need to be initiated before 1,000 feet and speed must be set by 500 feet.
