He knows better than to say no. If Kaldur says no, they'll just do it by themselves and then no one will be responsible because they'll be too busy egging each other on...

If they do end up on separate teams, I could totally see Robin just focusing on Clint and ignoring everyone else for the sake of war. He does still owe Clint a prank.
