But that break was typically how long it took to get to the next class. So it might have been a break from active brain activity (as evidenced by the brain dead decisions of navigating hallways/lockers), it's not a break per se. Maybe one was determined by the other, but I remember having to hustle to get from one end of campus to the other in those 10 minutes in a very un-break like use of energy

Yeah, personally I read it less as 50 minutes being some biological limit of human attention and more as once you go over people start thinking about how much longer you're going to be, how long it'll take to get to their class, weighing missing the end of this talk vs the start of the next one vs skipping their bathroom break/sprinting. Plus the added the distraction of people who have reached their limit getting up and squeezing their way past to leave.
