Curious EULAs

So I discovered a curious line in the Blood Bowl EULA:

This Agreement is effective from the day you install the Software. Your license continues for the shorter of: fifty years, or the duration of copyright protection for the Software

Most EULAs are perpetual licenses, if they're not yearly licenses. Why would you have a license expire in fifty years? And "or the duration of copyright protection" - wouldn't the license be unnecessary at that point, anyways?

Oh well. Guess I'll have to buy another copy in 2060.
