What on earth does 'a passport stamp ... "was not in use" on that date'

Does it mean that there was an issue date on the stamp and that this type of
stamp wasn't being issued on that date (ie that the stamp is a forgery)?

That was my understanding of it. Someone had copied a stamp for another
passport not realised that this was no longer in use.
