I can imagine this being useful to explain how a "difficult" UI element works. It seems easy to set up, I like that.
The way it's used in this demo, though, I found it's very distracting from the actual content. All my attention went to the little popover, which resulted in not reading any text on the page itself. I think this is partially because the popovers didn't point at anything directly.
