No it's not. I'm letting them know to apply for the non OA instead of the non O so they do not need to season 800k each in a Thai bank that makes 0 interest. It's an alternative that no one has mentioned here. Also the insurance to apply is only about 25k baht or less for a year.
I'm sure they can check with the embassy and decide the best route. It's an alternative not a confusion.
