If I ever saw an "annotate" command I'd immediately assume it's for adding notes as metadata outside the actual software versioning tool, not for seeing who wrote the code in question.

Nomenclature matters. Do not reinvent terms just for fun.

Agreed - I don't understand at all how the word "annotate" is being used here. It seems like "substitute" would be a better standin - as in "To whom can I attribute this code?"
