I admit that I dont exactly remember his first yellow, second was deserved.
One thing's for sure: FIFA needs to do something about all of the playacting and rolling around on the ground in soccer. It's BY FAR the most unattractive part of the sport and it really turns people off that are new to it.
I would put in a rule that says that if you go down and stay down for more than fifteen seconds you must be substituted or take an automatic yellow. That would end the acting pretty quick I think.
