ELI5: Why do speed skating times often get corrected several seconds after the finish?

Dutch athlete Michel Mulder won olympic gold today on the 500m speed skating event, due to the fact that his time was corrected by 0.04 seconds, about a minute after he had finished. Why didn't they get it right the first time?

When it comes to a fraction of a second, the human body just doesn't have that good of reaction time to accurately depict the exact moment they crossed the line.

It's not a single time they are given, it is from a multitude of judges, stop watches, and now probably tracking devices as well. They are then cross compared to give the correct time.
