I guess you mean a Non O-A one year visa. This visa gives you up to two years in Thailand, and it’s multiple entries. (You’ll need to renew your health insurance and apply for re-entry permit for your last year).
And you don’t renew the retirement visa, you apply for an Extension of Stay. The extension of stay based on a Non O-A visa also have a mandatory health insurance. You’ll need to leave, cancel your stay based on a Non O-A and re-enter on a tourist visa or visa exemption and apply for a regular Non O in country.
But to your point, if you’ve done consecutive transactions of 65K thb a month over sea to your bank account in Thailand while you’re on a Non O-A visa, I know people also have managed to use this to prove their income for a new Non O without bank 800K in a thai bank. (65K every months for almost two years from AUS). If this is possible at all immigrations, I really don’t know.
