Parallel Reflections II

Given are a required distance and direction. [These parameters are in red, and can be changed by moving the scrollbar and the head of the arrow of the vector on the semicircle] P is an arbitrary point on the plane, line 1 is the line through P in the direction perpendicular to the given direction, line 2 is the line parallel to line 1 at the given distance from it. Now reflect point A with respect to line 1 and then reflect the result with respect to line 2. How does Moving P affect the result?
