It goes like this,
If your application is complete, all the forms are filled , all the columns are filled, they Encash your DD.
Then they determine your eligibility ( calculate your points) if > 67 they send your AOR.
Since in 99% cases only those people apply who are eligible (everybody calculates the marks him/herself) so yes in most of the cases when DD i encahsed that means one will get the AOR.
Mostly applications are returned if people have missed some form, or have missed some column, in that case their DD or credit card is not charged.
