Yep, I did the same thing there when first learning it. I wanted to hesitate right there. You just have to keep that roll going right on to the next part. Having said that, I still hesitate after the second roll/crosspicking in measure 21 on the two open strings and it throws me off. They are almost like “fill” notes just to keep you on track. Hard to get my head wraped around those notes for some reason. 
Just wanted to say that Ben has done a great job on this and it has been a blast to learn. Every part in it is interesting and it has a great flow.I can’t stop playing it.
