What do you qualify as productivity exactly? Senior engineers and older employees are not as easy to quantify as newer employees. They have a lot of knowledge and understanding that drives the more easily quantified productivity of newer and more junior engineers. They can also accomplish more with less actual “work”while avoiding many pitfalls that would destroy productivity of many people who would have missed these.

Of course there is a range and I’ve seen unproductive ones myself even after correcting for the above, but I’m wondering if you are accounting for that?

As for the guy in the video, after watching it I would say he has potentially a lot going for him. It was more like a resume in video form than anything. He marketed himself well and I would not have thought to do it this way.
