No. In 1st and 5th, it is the outer roller clutch on the left side that drives the hub. This is because none of the sun gears in the planetary carrier are engaged, so no power is transmitted to the high speed roller clutch.
Whenever any of the three sun gears are engaged, power is transmitted to the high speed roller clutch, and the direct drive clutch is simply over run.
