Clojurians Log v2

I wonder what does https://github.com/quoll/asami/wiki/4.-Transactions#identity-values mean: > The entities in the previous example can be rewritten to use :db/ident or :id instead. However, using these ident values in :db/add statements has greater potential to interfere with tuples that should not be modified, so the use is discouraged. What can a [:db/add [:id "some value"] :some-prop "val"] interfere with? Thank you!
