Is not the aileron a give-away? When the heading starts to diverge, there is almost full counteracting stick. And just as you would in a cross-controlled slip landing to keep aligned, even more downwind rudder follows.
40:31 until 40:32,5 on FIGURE 2 from fdr. With the aircraft still on the ground, there is no corrective effect coming from the aileron deflection and the rudder makes the deviation worse. Once pitched up the effective span difference of the swept wing rolls the plane
The stick is back at neutral for rotation while the rudder input remains until after airborne.
