There is no discussion in the rules on how motors are connected. Remember, if its not prohibited, it is allowed. Rule 4, bullet 5 says:
  • MOTORS - You are allowed a maximum of four MINDSTORMS motors in the competition area. Choose your favorite combination from among the LEGO-manufactured types shown here. No other motors are allowed.
