I see the same problem lots with code that claims to be MIT and BSD licensed, but either doesn't include the license, or includes the license template with the placeholders for the year and copyright holder unfilled.
In the 90s it was common to see licence text refer to "the regents" even when that made no sense, but that's faded away as actual template licence text, meant to be used as a template, has become readily available.
I don't think it affected the interpretation much. If the author and the regents disclaim the warranty, and there are no regents, the straightforward interpretation is that the author disclaims warranty.
It makes complying with the license impossible.
