1.) Splitting object isn’t being deleted.
2.) Why does a split operation join the surfaces together instead of just splitting them?

Splitting object isn’t being deleted.

That’s normal. The DeleteInput option refers to deleting the original unsplit objects, not the splitter(s). There is not yet a DeleteCutters option in BooleanSplit

Why does a split operation join the surfaces together instead of just splitting them?

If you are talking about BooleanSplit adding the cap surface and joining it to the split parts, that is again normal - how it is designed to work. It is a volumetric operation, not a surface operation, like the other Boolean ops. If you just want to split the objects and leave them open, use Split instead of BooleanSplit.
