Executing certain techniques in sparring/competition

[Stupar Marko]

Fairly newbie question. When I watch videos of Fiore's techniques being executed it looks awesome but in competition or even sparring it's mostly trying to land a strike to the hands or a thrust. I understand being careful in competition but in sparring you don't have to worry that much. Are his techniques hard to do or do people simply try to avoid risk to the maximum most of the time?

This being an example. There are some others. No grappling, no disarms... not much.
