I think there is very simple explanation to King Street's withrawals.
Most of the claims indicate that King Street did their business with LBIE. Everybody involved with LBIE got their 100% plus intrests. Like most of the creditors, customers etc King Steeet simply filed in 2008 claims against LBIE and LBHI and other subs too. Now they withdrawed the claims that were filed "just in case" against LBHI.
