TLDR : Answer Summary

The 12-month extension for a Non-O visa in Thailand begins the day after your initial 90-day stay permit expires. Upon entering Thailand with a Non-O visa, you receive a 90-day stamp. After this period, you must apply for the one-year extension, which will then be valid for 12 months.

when you enter, you get stamped in for a 90-days stay permit. The Non-O Visa will become invalid. Then before this stay permit expires, you apply for the 1-year extension of the stay permit (based on reason retirement). The 1-year extended stay permit will begin on the day AFTER your initial 90-days stay permit expires

It's an extension. It extends your time. It's added on to the end because the extension you'll be applying for will be for the reason as the entry stamp you receive.
