I see it different
-----------------------------
1. Naruto is running to Pain
2. Before that he makes two clones , they run after Naruto
3. Naruto creates 2 Odama Rassengan in 2 hands
4. Naruto clones running after him , waiting and holding Rassengans to take them in time ( then Naruto finishes creating ) .
5. Naruto finishes doing OR , clones takes them and runs to summons , while Naruto is attacking fat Pain .
------------------------------
I dont say I'm right , I could be truth what others said .
