It's nonsense. They merely apply the same methods that they would normally apply if they were testing a car. However, with cycling it obviously depends on the individual rider much more strongly than with a car, where you do have some variability of reaction time and driving ability, but where the attributes of the machine are much more important. Some brakeless riders can skid to a stop in very little distance (and the police officer in the video doesn't really skid the way a rider would if faced with an emergency stop situation), others can't.

It often happens that if a pedestrian notices you as they wander across the road staring into their smartphone they stop dead. It's a roll of the dice whether they do notice you or not so it's impossible to predict where they are going to be when you pass them - hence always a good idea to slow right down. At 18 years old, I guess CA hadn't learned this lesson. You can't navigate obstacles in traffic based on the way you think they should behave.

It seems to be generally accepted that no cyclist or driver can stop in 7m at 20mph. The police skid reconstruction is daft. It's on a wet road where the copper rides up to a line and brakes suddenly. Not terribly scientific.
