If I get allotted a seat in 2nd round which is not my 1st preference

Friends please help !
AIIMS counselling
If I get allotted a seat in 2nd round which is not my 1st preference, then do I have to join that seat or pay a demand draft of 3 lakhs if I get my preferred seat in open round counselling?
The flow chart and the instructions in AIIMS website seem to say so. Please advise if anyone knows.
Thanks :pray:

With Rank 3050 UR not able to register for counseling , anyone know why?
