Another occurrence can happen if a player is low on health and they on purposely kill themselves so that the kill cannot be rewarded. This can happen by fall damage from high heights or jumping into the water.
In the evidence you've provided we can see that he wasn't on low health, he had more than 75% HP, and the rule states that it would be only counted as death evade if he was on low health. Anyway I'll issue a
warning.
