It's not really combat logging, he waited the 15 seconds and his ship survived. Not something I agree with personally, but he played by the rules.
@Draxxen - I guess it depends how long you want to stay out in the field without repairs. Personally, if my shields go down on the Conda, I'm jumping out anyway, so no need for a repair kit.
I've had my butt kicked twice in a Conda (turrets accidently hit a friendly cap ship) both times an AFMU or reboot wouldn't have saved me, the entire fleet including cmdr's turned red and obliterated me within seconds.
