Not universally true, but yes. I'm a ME by education, but we did this same thing in a class and my EE roommate couldn't figure it out without "another wire".
Few odd thoughts on this:
1) That's a great video. The point that if you can't know the basics, you can't know the complex. Why I want it hands on is exactly this.
2) The fresh EE guys out of college seem to have learned a ton about how to design integrated circuits, but have no idea how any actual electrical devices get wired. It blows my mind whenever they are in for interviews. The Mechanical Engineering
Technology people who went to county first so far have been the most knowledgeable.
3) I was at MIT once and snuck into a buffet for some student event when I was in my early 20s. It was organized with the long line of tables so that you can serve yourself from both sides. HUGE line on one side of the table. I awkwardly walked to the other side, walked down the buffet filling my plate. Then the students formed a second line behind me...
4) Completely off topic, but the same day I snuck into a Dental convention. I got a free camping chair which I still have.
