Unusual Flood betrayal. What gives?

[K0ldshot]

While playing Flood as a Spartan, another Spartan approached two of us but he had a red Player tag, was all grey as opposed to being yellow like the rest of us and he showed up as a hostile unit on the radar. At first, I didn't realize that he was a Spartan, due to the red tag, grey skin and radar signature. Both I and my teammate shot and killed him with no warnings. When he returned, he still had the red tag, this time when I killed him, I got a betrayal warning. He came back once more but was killed by a Flood and converted.

 

When I played back the match in Theater mode, I watched it in his perspective and noticed that both of us had red Player tags and also showed up as hostile on his radar. What's going on?

 

I have uploaded 2 replay clips to see what I'm talking about. Just search K0ldshot (the "0" is a zero) in the File Share Search.

The Fist clip is from my perspective and is called Betrayal 1

The second clip is from the other player's perspective called Betrayal 2

That is weird. It was probably a laggy host connection and your game was messed up. 343 has a lot of patching to do and they should add this to the list.
