A question starting with: 'A friend' .... I always have doubts about it. This 'Friend' cannot write or read himself?
Would like to see how this 'friend' completed the application form to give you an answer. All of this looks just as a combination of a mix of an application as Retired and Married with Thai woman. So not possible as it is the one or the other.
The only thing I can guess is: the former application and extension was as retired and the present one as married. In this case Immi wants to check you fulfilled the conditions on your former extension, 3 months after extension still had the 400K on the bank or income all year every month of 65K and now, as married, fulfill the conditions as married, so with the presents of your Thai wife, with pictures ........
