It is entirely possible that what Randall says is correct. It is also possible for it to be correct conditionally, because there is no way to know if Kabuto is aware of Mt. Myoboku, unless he went and said he was and I am forgetting something, and so he may have assumed that Ryuchi Cave is where all senjutsu came from.
