They are all in the first section
After the rising with dynamic tension ( a la san he) in bird stance,
the third deflect double finger strike, you know the one directed to the left
We are told to step with the right leg out to the right into reverse bow as we circle block and then spring forward into left bow stance as we finger strike.
Before the first hook elbow finger strike after you double finger strike to both sides with a call you step back with the right leg into reverse bow then circle block and double finger strike as you shift forward into bow.
Also after the first hook left step forward elbow finger strike into right bow then the retreating deflections into a low bird stance with a beak back and strike with the right palm. As you rise up from the low bird stance you are effectively in a reverse bow as you circle block and then shift forward into left bow again for the double finger strike
Also this seems to fit into the bird form descriptions that TTM put up regarding the way bird style involves darting in and out.
Well it seems that way to me anyway
