Yes it seems to benearly vertical to slightly closed just before contact
. The reflection from the strings happens only from contact.
The consensus from the other thread is that if the ball is contacted in the lower half of the strings (lower as in racket horizontal), then the recoil will cause a slight closing of the face even on vertical (or what you call square) impact BUT it is also the case that the face is often deliberately closed around 10 degrees to control a ball taken on the rise.
