Kicked From Ranked Survivors For Self-Destruction AFTER The Round?

Here is the situation. I absolutely love the new Ranked Survivors game mode and playlist. It’s fun and exciting. If you follow this link you’ll see my anger and frustration. The video is edited down and here it goes.
At the end of each round and naturally since 2001 when a game or round ends I throw grenades at my feet and blow myself sky high. In this video you’ll see me kill myself three different times and on that third time I get booted from the match and then banned from matchmaking for self-destruction. Even though it’s once the round has ended.

What are your thoughts on this?
Have I missed some glaring information from 343i on this topic?

Thank You
