In my experiance, the examiner wants to see you screw up. Then they want to see how you react to that and if you can recover the technique/turn it into another one or otherwise keep on top. Your attitude during this is obviously important too, its no good looking like you screwed up and being annoyed with yourself. You have to look like you meant to do that and that nothing can bother you.
That seems to be pretty accurate. I think that earlier on in your training they are really looking for you to keep moving.
