Yes, it does matter when your transform.localPosition is not same as transform.position since your point of origin for Raycast will change with use of either of these.

The transform.localPosition gives the position of your object with respect to its parent whereas the transform.position is the world position of your object. So if your object has no parent game object then your transform.localPosition and transform.position will be the same.

transform.localPosition is always with respect to the parent of the object whose localPosition you are accessing.

In your case just use transform.position of your player.
