If you go from first kill in clutch to the last kill in clutch, then probably that, yeah. Oskar actually had a awp triple collateral to win a round, but he was in a 1v4 and had killed another player before that so his time from clutch to last kill is longer.
In general, if you focus on "fastest clutch", then it's probably just someone tradefragging in a 2v1 but that's lame.
probably some 1v1 trade "clutches"
A “1v1” where someone just trades a sec later
Holy shit that was so sick
