I feel honored to have been cited, but I am absolutely not an expert! When I created the video I was incorrect in my assumption that the bricks were timing out based on number of sweeps. They absolutely timeout based on time.
The issue I was actually alluding to was not, however, how the bricks timeout, but rather how that setting affects trackfile deletion. As a general rule for myself, I never delve into official documentation, so I'll let someone actually familiar talk about this particular issue.
