I think its impossible to leave the gate at T-9 if they truly closed the door at T-10. They probably then did close the door more than 10 minutes prior to scheduled departure.
More, the reason I wasn't at the gate T-15 was due to their mechanical failure. And they knew (or should have known) this.
I sent in a request simply based on the fact that their 20 minute mechanical delay resulted in a 7 hour delay for me.
