While I think they make relevant points, the underlying logic of this whole video is questionable.
Before the recent changes, "Jamie Oliver" simply didn't show up when searching for "cooking", I expect. It didn't matter if his twitter or G+ page were the first result for him, because they were probably on page 800 of the search results.
Now, with the additional info it has via G+, Google is featuring him and some other people alongside the normal results when you query for Google.
Where Twitter falls in the query for "Jamie Oliver" doesn't seem particularly relevant to that. I understand the thinking, but I don't think it makes sense to say that because Jamie Oliver is a top G+ result for "Cooking", and Twitter is the top result for "Jamie Oliver", then Jamie Oliver's Twitter must be the top social result for "cooking".
The OP is assuming that search results are somehow transitive in nature, and I'm don't think they should be just taking that for granted.
Should Google add links to the other services in those G+ listings coming up alongside the results alongside the cooking SRP? Maybe. But that seems like a UX/business question, not one that you can answer quantitatively.
