should this be removed as well? if not, why Boolean => Integer?

oh, thanks for catching this. 
I removed it at first but noticed that the javascript needs to know which
categories it's going to receive in order check if everything has been
calculated and when to update the total number of items that are going to be
deleted. The initial value is false (line 950).
I must have copied the line from above when I added it again.
