Snowballing a Dead Champion as They Respawn

First time ever posting. As the title implies, snowballing over an enemy champion's dead body just as they respawn sends you to their base however I don't know about a teammate's body.

I do have video proof of it happening: [WARNING] These videos do have swear words in them.

Vi then goes across the map to where Mundo is. (watch the map)

I don't know if this is an actual bug or not. But I do find it hysterical.
