You are wrong. slots is the mechanism whereby "different versions of a single package can coexist on a system". "Setting a choice" I assume means your eselect-style choices. For example, you can eselect a pager, which has nothing do do with slots. Or you can eselect the system python, which does (indirectly) have to do with slots. But eselect and slots are not the same.
