Yeah, I've seen stuff like this happen to enemies, teammates, and myself. I'm glad you saved vids so I know it's actually happening and someone wasn't camping.

Whilst spawning near teamates is helpful, it doesn't seem to take into account map location or enemy location into account that much.
Don't take life too seriously, or you'll never get out alive
