Oops. Sorry for my cut/paste error. Fixed in patch v6.

Sure, it might be a bit shorter to combine the examples, but I thought
it’s just simpler not to do it that way because the combined example
will then need additional bullets/notes to say – “if there is no
slot_name do this…” and “if there is a slot_name do that…”. It’s
really only the activation part which is identical for both.
