rubik - it has (in my world anyway) always been a given that a crew would check the door lights after an abort before moving off so your 'scenario' should not occur, plus it is to be hoped that the c/crew would NOT pop the slides unless the engines were stopped AND it is 'normal' for the pilots to make some sort of call to the c/crew after an abort, normally 'remain seated' or similar while the situation is assessed.
Also in reality we are moving into an 'event' which has a low statistical probability of occurrence and these are often taken as 'accepted risks' in our business. Never-the-less, as I said, a good topic for refreshers. I agree with the first part of 'This is the industry standard and considered best practice when it comes to initiating an evacuation, go back in your corner and be quiet" but whoever this discussion was held with needs a little 'education' over the second.
