you got your wires crossed . . . . with a multi entry Non-Imm-O visa you are not doing any 90-days reports at all. Because you will have to leave Thailand before your 90-days stay permit exspires. Thus, your 90-days clock starts at ZERO when you re-enter Thailand and get stamped in for another 90 days . . . . . .. ONLY when you changed from the visa to a "1-year Extension of Stay", you will need to do 90-days reports.
