There are no "thoughts or opinions" about what the newly-signed OC law states - which is you must have or obtain an Oklahoma CWL in order to carry a handgun either openly or concealed. The open carry provision goes into effect on 11/01/12.
I think the confusion he's getting may be coming from the fact you may open carry on your own property or property controlled by you without a handgun license. However step off of your property and you MUST have a handgun license to carry open or concealed.
