Can't pass bomb?

There must be somethin going on, because as it's explained that you can't pass back to the person who gave it to you, it's also stated that, I believe, 100 passes between the same 10 people(?) can get the better box rewards. Yet, when it comes to the event in the game, people are stating they cant give the box back to anyone who held it previously...

What's even more confusing, is after hearing this in-game deal, someone who had held the bomb previously was given the bomb again, yet everyone in-game still says you can't pass to people who have held it. They stated that the guy getting the bomb a second time was a glitch. So, maybe someone can enlighten the subject?
