3 team trade?

Hi

several people kept saying that they are thinking about a 3 team trade here... but how is that possible in a dynasty?

basically, all trades need to go through you, so it really is two 2-team trades

Milwaukee
Gives: Joe Smith and Ersan Ilyasova to Miami, and Reece Gains to Atlanta
Gets: Marvin Williams from Atlanta

Miami
Gives: Udonis Haslen and Earl Barron to Atlanta
Gets: Joe Smith and Ersan Ilyasova from Milwaukee

Atlanta
Gives: Marvin Williams to Milwaukee
Gets: Reece Gains from Milwaukee, as well as Udonis Haslen and Earl Barron from Miami

So Udonis Haslen and Earl Barron are also from Bucks to Hawks?
