I've noticed that sometimes, a highlight video or the Play of the Game has the text "Lifesaver" appended during the intro, usually below the hero's waist. However, I haven't noticed any differences from the usual "get a significant multikill or capture" videos.

What causes "Lifesaver" to appear, and are there any other similar modifiers?
