Time travel

Another curious footnote to the Tale of the Incompetently Censored Prisons report. The bolded portion of the following text was redacted in the original:

The incumbent will return from maternity leave in September 2008.

The date, and the choice of verb tense, are the sorts of things you would write in a report in August 2008, or earlier.

Yet the report — here's the link to the .pdf file — is forward-dated October 2008, a month after an event which is described, in the report, in the future tense.
