Yes, exactly. I did ask the HDB officer about this issue during my flat selection last month. What they told me is that they will only look into your income ceiling during the application and flat selection. Subsequently, they won't be looking into that anymore. During your key collection, all they will assess is how much you can and need to loan and whether the loan is from HDB or private bank. That's the reason y they will need a reassessment of your joint income and HLE to determine how much you can and need to loan, not for the purpose of double checking whether your income has exceeded the income ceiling.
