yes exactly! The bit you point out is with the aircraft cross controlled but not yawing, it is slipping (due excess rudder) but basically tracking in a straight line. You can do that in a Citabria (in the video a Decathalon) and it won't bite. Similar to how you would side slip to lose height on final.
If however you are cross controlled and yawing due excess rudder (ie skidding) and it will bite. Similar to trying to skid it around on a base/final turn and avoiding too much bank. Stall then in the Citabria (and Decathalon in the video) it enters a spin really smartly.
Why I suggest saying use rudder to control yaw NOT to "pick up a dropped wing".
