Perhaps it was some misunderstanding here. Even to get 1 year extension inside the country need to seasoning 400K during 2 months and then wait 30 days while consideration i.e. totally 3 months. What they may request it is showing current bank account balance is not less than this amount like in some other consulates. 

This is what consulate answered me when I contacted them by email:

"It is possible to apply for a multiple-entry Non-O visa at the Consulate.
Please see details of the required documents from the Consulate's website at

https://savannakhet.thaiembassy.org/th/publicservice/non-immigrant-visa-o-visiting-family-member-of-a-thai-nationality-a-sp?page=5d84a44c15e39c26b400453e&menu=5d84a44c15e39c26b400453f 

For the multiple-entry, the evidence of adequate finance (6-month financial statement from Thai bank with the balance of 400,000 baht per person) is additionally required to present to the Consulate upon visa application submission."

 

I definitely don't think they expect the money to be seasoned for 6 months but as I had the 400k for more than that, I didn't ask for more details.

On previous recent reports here, OPs mentioned they put the money few days before applying for visa and it went well. However, as things changes quickly these days, I'd recommend contacting the consulate before applying to know exactly what they need.
