I shouldn't try to speak for Donny, but knowing what I know of him, I THINK that when he is using a style he likes the progression from Var 1 to Var 2, 3 and 4 ... HOWEVER, while he may want to start with Var 1, he wants to use the voice settings of STS2 ... which apparently the KB will not let him do ...

If my GUESS is incorrect, I apologize ...
