Yes, if you take the new OTA (NC1) you cannot root it now with saferoot or any other current tool.
And yes, you can ODIN back to ML1 without issue and reoot using saferoot (I have done so.) Well, one issue: Your phone will be wiped clean and you must reinstall all your apps. ExtSD card should remain untouched.
Hopefully, new tools will be developed to allow rooting NC1, although the update is really minor and not needed for most people. The big question is whether once KitKat rolls out for the S3, will it be able to be rooted.
