NO. to sweep you have to sweep the entire passage in 1 movement, now if your playing downstrokes on the way up, you arent sweeping, sweeping is going across the strings in 1 pickstroke, e.g. you do 1 long strum and play 12 notes. To sweep you have to use 1 downstroke for notes going from low e to high e and 1 upstroke going from high e to low e. Six notes in each direction with 1 pick stroke. The idea of sweeping is so you dont have to continuosly pick each note, when you sweep you get 12 notes for 1 pickstroke.
