FINA and Cards

Hi, In reviewing Appendix A and B to the FINA/USAWP Rules 2009-2013, I noted instructions for issuing yellow and red cards that seem to differ from previous instructions, and I am just looking for clarification/confirmation.  

A.7 -- "If, in the referee's opinion, a player persists in an unsportsmanlike manner or engages in simulation, the referee shall issue a yellow card to the offending player."  Yellow cards are no longer reserved exclusively for the head coach, and they may be issued to a player in the water still eligible to compete?  What types of situations warrant a yellow card to a player in the water versus Misconduct (21.10)?  Is the purpose of the change to move some of the actions that in the past resulted in exclusion with substitution to a yellow card, or is the purpose to address "minor" acts of misconduct with a yellow card because officials were hesitant in the past to whistle such acts since the consequences were severe?  Are we moving away from the "old school" idea that if you make one comment to the referee, you are done for the day?  (If so, I think it's a mistake). 

B.F -- "To signal the exclusion of a player for misconduct.  The referee signals exclusion accordance with Fig. D (or Fig. E if appropriate) and then rotates the hands round one another in such a way that is visible to both the field of play and the table in addition to issuing the player with a red card."  (In B.G, similar language suggests a red card is issued for exclusion with substitution after four minutes).  Red Cards are no longer reserved for behavior on the bench--coaches, players, representatives--or for excluded players who remain in the water?  Is the Red Card now just an explicit redundancy that signals that the person must leave the competition area?  

Thanks,

David
