i have never seen the form, but I assume they are asking why you are staying in Thailand, when you extend the non O visa you get a stamp with a date of expiration 1 year forward, the stamp just gives you permission to extend your non O visa.
There is no such thing as a retirement visa, you can apply in your home country for a 3 month non O visa if you qualify, then you can travel to Thailand and extend it for 1 year, provided you have the documentation, and extend it every year going forward, it is easy just stick to the rules.
There is no ban on leaving and no restrictions, it was the Laos immigration that refused him entry because they know he was abusing the system and are helping the Thais clean it up, and also being pissed off by people coming over the border for a few hours.
you've already had 3 months, and you want another 6, that's not a holiday, you're trying to do border runs to cheat the system, why don't you get the correct visa instead of being a total prick and fucking it up for everyone else
It is precisely for people like yourself that they are changing the rules, you are trying to live in Thailand but without obtaining the correct documentation and paying for the priveledge
You should not have a problem entering again, immigration are looking for people trying to stay long term in Thailand without the correct visa, you are not extending your 60 day stamp you will be ok.
