In fairness the OP does state: "...Make sure that you understand the implications of this script on the backup and recovery of your database(s): Managing Transaction Logs."

The linked article was: http://www.sqlservercentral.com/articles/Administration/64582/

I agree with other comments posted to use caution and be wary of using the script. To that end, perhaps the OP could have made this above statement more prominent or provided ample warning/comments within the script.

As with consuming any scripts posted on the internet, one should be reviewing the script and understanding its use/impact and testing within their own environment before moving into production.
