yes it does. Arriving in Thailand with the Non-O visa will allow you to open a bank account, you can put as much or as little into the account as you wish. However if you want to apply for the 12 months extension of stay you must have 800k baht in your thai bank account for 2 months before you apply for the extension. Note that's not the day the 90 days you get stamped in for runs out, it's the day you apply. It's not a good idea to run it down to the last days
