You're posting top 10 moments in a game to a competitive gaming forum, of course people will value stuff that is rare as all hell and includes rolling the dice just right over some play that doesn't take equal amount of skill and luck.
It's like in cs when someone hits a jumping shot and clutches a round, yeah it's a bit luck based but the rare chance for something like that happening; in a high stakes moment nonetheless is what is important to spectators of esports.
It can also demotivate a lot of people from submitting plays if an airshot like Alfie's get's 4th place and a pyro holding m1 and a demoknight bomb gets placed above it
