Use case for BatchUpdateInstancesTransform

I wonder, which might be the use for the Blueprint Node BatchUpdateInstancesTransform. Not talking about BatchUpdateInstancesTransforms, which makes perfectly sense and works fine.

But that “single transform” for “many instances” function does not make sense to me, as having different transforms for each instance is what instancing all is about.

This node instead applies the same transform to all N instances beginning from start index. So they all end up at the same position. I tested and found no useful application for this, above image shows some test having 5 instances overall, and just updating the first 3 of them. As expected, these first 3 collapse to the same point.

I could for example understand a BatchUpdateInstancesRotation to apply a rotation change to a batch of instances while preserving position.

Looks like I’m missing something, so anyone can bring some light to my darkness?
