“If I understand correctly, the index references the individual points of the curve. The points created by the resample curve. And this operation here takes the index (integers between 0 and 5 if count is “6”. Then this is divided by the count. So, 0/6, 1/6 … 5/6.”
That is absolutely correct!
Those values then go into the Factor of the Sample Curve; consider the Length of the Curve to be 1, then 0 is the start of the Curve, 1 the end and 3/6 is exactly halfway, etc. I then use the Tangent of the Curve (Circle) at those 6 Points:
As to the other question, you are correct, to be precise: the Nodes before the Combine Node, give a Value and if you plug a Value into a Vector Socket, that Value is used in all Components of that Vector, so yes, like you say it would affect all 3 Axes in this case, hence the Combine XYZ Node
