I bought four rolls. Two rolls start at the identical point in the pattern. The others start at a different point in the pattern.
I have never had this with ant other wallpaper I've bought.
It means for each roll I can get 4 strips for the first two rolls, but only 3 strips for the other rolls. 
Its a waste of money given the price of this product. Why couldn't the manufacturer cut the paper at the same starting point for all the rolls.
And yes, the pattern number and batch number is the same on all rolls.
