> Thanks for your answer. Is the component of the velocity in direction normal to the wall inverted as well in this procedure or not?

velocity is a vector. And vector is just a direction in 3D space. It
cannot be negative, and cannot be inverted as 1/x. How can you tell
if vector (-1,3,-4) is negative (or inverted?).

So the answer: no, the velocity is not inverted.
