Yes it does. The fact that it moved faster than gravity is not special in and of itself - many things do that when acted upon by other forces (e.g. if you thrown a ball towards the ground, and in a similar case mentioned by another commenter). In the case of the plane though, the question is why? Was it a failure of the avionics package, erroneous input by the pilot, etc. Knowing the cause will help understand and mitigate the risks moving forward.
