Not to be an ass, but... What is so special about that anyway? They're both in the same spot, and on Domination at point B, which is commonly rushed by the both teams and gives easy multikills. The first one, even less so. They seemed to already have been hit by several grenades from your other teammates, yours just dealt the finishing blow.
Edit: Dolphin Dive fail. I had a good laugh at myself when this happened.
