Teaming does increase the possibility of winning, but what he was trying to say (in my interpretation) is that teaming and only one team member is getting the reward of actually winning, then it's not allowed. The only exception I can see is if a team does a fair fight and one person is just better and wins every time. For example, me and a friend team for 3 games. He is better than me, so when we fair fight at the end, he wins all 3 games. BUT if I tell him /kill so that I am getting the win every time, that would be considered boosting. And as I said before, if you alternate wins, such as he won the first, so I win the second, it wouldn't be considered boosting.
