This is correct. I have a large media library and I wasn't sure how rotted it was. Test decoding won't catch every error, but it identified albums where there has clearly been a bitflip in a song (at which point I can try to find a lossless copy of that song to replace it). Once I'm happy with the state of the library, I use automedia to add on par2 files to avoid this going forward. Verification is for libraries that have no existing hashes or parity, essentially.
