That is the exact topic illustrating what I described. (I would usually refrain from commenting about academic subjects on ladder clanwar webpages.)
However, I think that point, about 2-sided anatomical sensory mechanisms; such as the seeing eyes, the nose and tongue of taste and smell, the ears that are able to hear audio and detect gravitational balance and also to observe and predict magnetism; the point relies on the presumption that: "ladder will only cater to people with extraordinary vision" and the notion of cephalization can help to explain why personally I usually don't think watching a video showing (in reference to the CTF video record) 2 separate screen-capture-videos, displayed side-by-side.
Cephalization is a term regarding evolution that describes an evolutionary lineage or a chain of attributes among groups of lifeforms (like… fishes, amphibians, tetrapods…) and "cephalization" means the anatomical development of a skeletal skull within the head wherein the brain recieves sensory input information via the aforementioned "eyes and ears" and thusly can similarly direct output information (in other words, to communicate) through vocalization, "eye contact" (during which the sets of eyes of multiple individuals mirror those of the correspondants), among a variety of forms of communication that would be culturally listed as languages.
In the classificatory clade of animals exhibiting cephalization, there is binary distinction among 2-eyed groups between those with "predator vision" and eyes that face forward with a more narrow angle of light-detecting-beam rays fom the cornea to the object at the focal point, and those with "prey vision" and eyes that moreso face sideways with a wider angle of focal rays.
Regardless of the distinction between predator vision and prey vision, both of these groups of animals rely on their vision for survival (in the contexts of seeking and obtaining food and avoiding physical harm) as the descriptory terms indicate. Thusly, I don't actually think it's helpful in life to expend the energetic resources of a vital sensory mechanism to visually concentrate on (what essentially amounts to) a video that requires the eyes to be desynchronized in order to watch 2 screen at once. It would be a lapse from concentration, and regarding anatomical mechanisms, that is typically actually both doing excessive effort and habitually dangerous, in the overall scenario of life aside from watching CTF ladder clanwar videos.
With that allusion having being explicitly revealed — I don't think my prior comment that "this video is not worth watching" actually warrants a shift of focus and divertment of the scope of the webpage from the game of pertainance toward a series of explainatory academical remarks.
I think the video format of having two screens side-by-side is not watchable. I personally am not capable of attentively watching either screen when both are displayed side-by-side. I'll acknowledge that it's just my personal opinion, and I don't want to try any further explaination of my rationale, nor am I trying to incentivize doing unneccessarry work to offer an alternative; just expressing my reaction to watching the begining was like: I cannot watch this, I cannot focus on two side-by-side videos simultaneously.
