I'm not sure about that. When I interviewed at Google, everybody seemed very impressed that I finished half my Honours degree before I graduated from high school at age 17. I had far more questions about my experience with concurrent high school and university than I did about doing my doctorate at Oxford.
But on the broader point, I absolutely agree -- if I was looking to hire someone, this would get an immediate reaction of "this takes way too much work to comprehend; trash it and move on to the next candidate".
