Always difficult to know what one is thinking but you go through on 747 wake and it may be a surprise even if you discussed it before takeoff. Now you perhaps think quickly if there is a way to try to smooth out the next encounter for the pax in the back. Why not try rudder to reduce the effect. Turns out that Airbus designed a plane with overly sensitive rudders that you didn't realize can easily go full deflection.

Oops, the first rudder input did a huge amount of yaw, better bring it back. Oops went too far the other way with these small pedal inputs that have a large effect. Damn, I am overcontrolling it, good thing we are relatively slow. CRACK.

Meanwhile, the captain assumed that it was bad wake turbulence from that heavily loaded 747.

Only a guess of course.
