Would be interesting to know how they timed that, if its the time between the car stopped to car going that is a very impressive time.

Only a few ways to reduce a pit stop time, you can shorten each movement, speed up each movement, overlap movements simultaneously and reduce the number of movements.

Car positioning is probably the most critical effect on time as if the mechanics all have to shuffle along from their set position, then they will be slow.

There is so little margin for error the team that does it with the minimum number of mistakes is usually the fastest.

Changing on the wheels automatically on the fly was considered by some teams when they went from fuel to no fuel stops, the FIA stamped on that pretty quickly.
