What did you expect to see?

With snippets, for extract function/method/variable, we can change function/variable name in two places at the same time; for fill struct, all the right side of property assignment can be a snippet node; and for generate missing function/method, we can select the panic("unimplemented") so user can replace it right away.

I think the intent of the video is to illustrate that applying the code action causes the selection and cursor to change, not just a mere text edit. The mechanism is similar to a snippet completion, which returns a snippet of text with placeholder fields in it.
