Bank Statement for Extension of Retirement Visa

Although my next extension is not due until December, I went to Bangkok Bank to request an account statement. I wanted see exactly how it looks in case it does not comply with Immigration. The clerk understood (at least she said she did) that this was for Immigration compliance. It took about 5 minutes and 200 baht for me to get the statement.
The transactions where I moved money from outside Thailand to the local bank are marked as BAHTNET via USER. I see no evidence that the deposit came from outside the country, but possibly BAHTNET means something ?
I questioned this with the clerk who told me this was what Immigration wanted and she also gave me a letter stating my account status and date opened. All stamped and signed.
My question is: Is the clerk correct ? She certainly seemed to understand what I was asking for and there was no hesitation or uncertainty is her actions.
