Thanks for your comment! (I'm the author of the image/poster). At first, I wanted to give a similar explanation than yours, but then decided to make it more verbose / less technical, and it ended up having more text that I would like to. Also, your last sentence is a great summary of when they should be used. I included a few use cases, but I should have also included something like what you said. I'll take that into account for future posts, thanks!
