Hi Frank,
If you use a Connect object with Octane Object tag, before the Cloner, you don't need to freeze the spline primitive:

Do you know what the internal logic of it is?

Probably because Octane Object tag can't be cloned using cloner or it doesn't works for hairs and it is enabled only for one spline. Connect object connecting all cloned splines for one object and after that Octane tag works for all clones because it treat them as one object.
