If Position Influence = 0, there is minimal movement of the CVs on the Input surface.
If Position Influence = 1, the Input surface tries to match the parameterization of the Master along the aligned edge, causing lateral movement of the G0, G1, G2 and G3 CVs. The G0 CVs will match the CV locations on the Master surface if they are in equal numbers.
Position Influence = 0
Position Influence = 1
