Does this feature suggest they understand what was said? I'd expect the button to light up at random times in a video about "smash the like button" causing the button to light up, rather than in the end call to action for the video where the video author actually wants the watcher to click the button. Similarly, I doubt it can properly understand when the video presenter implies the term "smash the like button" while instead say, leaving an empty space where they would usually say such a thing. If I pointed you at some french text and asked you to point at the term "le Chateau" you'd be able to do that without understanding french.
