While admittedly a bit confusing, this is working as intended; Each Shape Key Helper describes the rotation at the end of its corresponding bone.

I admit this could be better, but fixing it now would be a very sneaky and nasty backwards compatibility break. I don't usually mind, since CloudRig ends up needing to be strictly version matched with specific Blender versions already, but in this case, generating an older rig would run without errors, and users would find that all their shape key drivers are suddenly targeting the wrong bone. I'd rather leave it as is, for now.
