In yoyo mode, the pulling force is converted in energy, unlike (at least partially) Figure 5 configuration.
Let us analyse a bit what we see on the video below (also from kPower LLC filing - #58 by kitefreak), just after the indications:
If we see carefully the system during these 9 seconds in full screen and with stops, we can see the two anchored pulleys at the left and right to the skateboard, and the triangular rope sliding during the flight and moving it.
So, Figure 5 has therefore been made and shown on the video above.
I can observe that the range of motion of the skateboard is very limited. I could deduce that the applied force by the kite looks to be limited as it is not directed towards the move of the skateboard. A large part of the force is lost due to the traction exerted on the anchored pulleys instead of actuating their rotation. Thus a minimal part of the force is applied to the displacement of the skateboard.
