It's essentially the old school version of "turn it off and on again", but the physical ritual aspects of reseating the cart (which was helpful) and blowing on it (which was likely placebo) made us felt that we made some effort to make things work. It's one of the weird details that adds to the experience. In comparison, the modern "turn it off and turn it back on" just don't have the right tactile feel to it. Except maybe when power cycle doesn't work and you have to pull the battery.
