Does Close Combat snapshot distance at start of attack?

Trying to decide between it and Elemental Focus for Serpent's Fury. Tired of its knockback mid-animation.

I bet that it works like Proximal Tangibility. Close Combat probably would only use the distance between you and the monster at the moment when a hit landed, ignoring everything else, like skill animation's position and the place where your char started moveset's animation (before actual hit).

But I can't be 100% sure of that.
