The article gives the rowing example and I think it is a great one (maybe the best one) where there is theoretically infinite air, but the motion creates mechanical limitations.
In running, once you get the intensity high enough, its almost impossible to inhale during push off because of how the abdomen and diaphragm are compressed. Running push off is not that extreme, but if you make the hill steep enough and you have enough knee lift at high enough speed, you end up with the same mechanics....at which point you'll just naturally avoid breathing in as you are pushing off. These same mechanics show up in speed skating and XC skiing too and many weight lifting exercises....so we just breath when its most mechanically advantageous....how many times we breath per minute, then factors in mechanical limitations of when it is natural to breath and how much oxygen we need (hard rowing, or hard butterfly stroke are great examples when you have high O2 needs, but also mechanical limitations (if you did hard lat pulldowns the same way as swimming fly you would breath in at exactly the same time even if you have infinite air).
If the mechanics of the sport did not limit when we breath, then you would not get all the 8 rowers in the boat also breathing in sync (since they could all choose when they want to breath with infinite oxygen access). So that's probably why this article in outside found that highly trained runners fall into a certain breathing pattern, because they are running fast enough and applying enough force that timing of breathing limits mechanics of force.
