As we see here,Obito sent his body to the other dimension,so Minato didn't have a chance to attack him .
Here,he just Kamui'ed his head beacuase Minato's kunai .
He might have seen Rasengan coming .
And here :
He got owned by Rasengan .
My point is : Why didn't Obito kamui'ed his whole body just to be sure ? If he kamui'ed it,Minato's rasengan would miss,and Obito would capture Minato ....
Or maybe it is that obito didn't masted his sharingan in that time ?
