But home and away are totally arbitrary in this context, with the exception of Qatar. So how does that characteristic provide any benefit from an analysis or presentation standpoint?

Oh yeah generally youre right, but the data was also ‘doubled’ in this way. Because each row is a match, the variables are present for each team separately. For example: there’s attempts from outside the box by team1, and attempts from outside the box by team2. The pattern of relation should be symmetrical because these differences are arbitrary as you say.
