The ball does say that how everyone's lives are used are up to them. All the members of the Osaka team seem to not care about death, so they probably come back to life everytime. However, that's probably not a good idea since people tend to not care as much about winning if death isn't a factor. The true potential is lost.
Aside from that, maybe the new team has different things that happen at reaching 100 points. They do have different weapons.
