This is a more bruteforce method that some lower-quality tools employ. Instead of "cracking" the password, the software sends a command to the PLC to forcibly clear all user memory. This completely deletes the protected program along with the password, leaving the PLC empty and ready for a new program download. The tool essentially "unlocks" the PLC by wiping it clean. While it restores accessibility, it permanently destroys the original program, which is often the very asset the engineer was trying to protect or analyze.
