The first one was the reward for the ecclesiastical princes who cast their vote for the election of his son, Heinrich VII., as roman-german king. The second one was a reaction of Friedrich II. towards the secular princes who he couldn't effectively govern from Sicily (and while Heinrich VII. remained in Germany he wasn't much more succesful) but who he needed due to his conflicts with the Pope. Thus the Statutum was in effect a bribe to guarantee their cooperation and loyalty - which worked relatively well as although two Counterkings were instated, none of them were succesful in amassing large support of the princes. Nonetheless after his death the dominion of the Staufer ended in the HRE, the Interregnum began and the princes were able to further expand their territories and entrench themselves.
