Honestly, I feel like it's because the game forcibly turns you whenever you bump into a wall. I do wish this feature was removed, because it's frustrating when I'm jumping around on rooftops/cliffs, but the game rotates my character immediately after bumping a wall (doubly frustrating when I throw my axe, but a teammate bumps into me, causing me to auto-rotate and fling my axe off a cliff)
Forced turning may be affecting this, but from the clip it is not 100% clear. There is a lot of tuning on the forced turning to make this feel just right, which is something we are tracking. We have revisited this for 0.8.0 and plan to continue updating this with more traversal in the future.
This can feel frustrating during hunts, so it is something we are keeping a very close eye on <3
