I think it depends. I had mine on hold til 10-1 and last night my EDD was October 17 - November 14.I had put my order on hold like 5 days before delivery (Sept 26) in order to see if this bill was going to pass. My hold just released and new EDD of March 16.... ouch. I guess your spot in the queue is reset if you put your order on hold (guy on the phone definitely said you would get back into front of queue).
EDIT: Ruh-oh, now it's Estimated Delivery: October 07 - October 11
Another hold? Crap!
