This red stamp itself is not a visa. This stamp is a 90-days stay permit you get stamped when you enter Thailand on a 90-days Non-Imm-O visa.
The stamp just indicates the “admitted until” length of stay – here 90 days - based on entering on a single entry 90-days Non-Imm-O visa.
The visa itself, when he entered Thailand, has changed its status to USED and is not valid anymore.
