update.php problem?

[deconstructor]

I installed cpg1.4.3 and everything was fine. Patched the new security fixes and things looked good. I was looking around and found update.php in the root dir cpg.
I ran it thinking it would a least ask "are you sure" or something. Versioncheck says it's a required file. Well it ran and it chnaged/altered some stuff in the mysql tables.
Everything seems to still be working but update.php should check the lock file that install.php puts in so this doesn't happen. Should i reinstall ?

You can run update.php as much as you like, it does no harm.
