I think the scroll found by Suigethu is the scroll that described in chapter 1. I know that scroll is bid Orochimaru would have summarised jutsu in to a small scroll.What if Orochimaru wanted that Scroll and he Mzukki I know he failed.Then You will ask how he get that scroll? the answer is at the time of chunnin exam.he would have taken the scroll at chunnin exam.
The reason why I think that when third hokage , jounnins and chunnins knew Naruto taken the scroll they have a terrible feeling in thier face plus it is said that it is the scroll first used.

it is said forbiiden ninjutsu sealed in it Orochimaru would have read that seal and would have written the deatails in the small scroll suigethsu found.
I don't think it is rds YOu know Naruto's ninja life started from that scroll what if it has some important in this war........everything has similarity his firat technique was shadow clone that too first written in scroll...I think kishi puposefully done this
