ELI5: During a live televised sports match, how do they get the replay footage edited in so quickly?

I’m curious as to how a ref will blow their whistle and get instant replay footage within seconds. Can someone explain this process to me?

There's a whole room (or trailer) full of directors, producers, and editors watching dozens or hundreds of feeds simultaneously. They're pretty much constantly cutting highlight shots, different angles of play, etc to be ready when the lead director wants a replay.

It's a huge amount of very fast-paced work.
