Can you stop dialogue after closing it?

I have dialogue playing and I would like to be able to stop it short in case I want to play something else. I figured out that if I don't call DynamicSequenceClose, I can call DynamicSequenceStop whenever I want.

But for dialogues that does play fully, I want to listen for the AK_EndOfEvent callback and it doesn't happen unless I call DynamicSequenceClose. Am I doing something wrong?
