But generally we use empty lemma references to refer to things that are not present in the text. That is not the case here, as the word "spes" actually is there.
variation-present can't really be used, because that is reserved for cases where one witness has a word that is not printed in the text. So I suggest here variation-substance, but others may be better, I don't know. But the point is: The reference word is actually present in the text, it has just been repeated by one witness.
I'm not sure I agree with our decision to make annotation of iterations required to have empty an lemma.
The documentation says:

A more natural annotation seems to me to be:
Giving (with proper processing):
