iTunes Match uses a combination of the tag data, song length, and audio fingerprint to try to match the track to an existing song in the Store.
Because of the audio analysis, it may get around incorrect tags in some cases.
It is not 100% correct. Match users are full of stories where it mistakes Clean vs Explicit versions, live vs studio versions, Spanish vs English versions, or it just plain messes up.
As Apple recommends, make a local copy on an external disk drive so that you will have a valid copy of the original song.
