I would say the latter... but it still didn't get me far enough and I managed to do the same thing a 2nd turn as well, lol. for the most part, it looked like even though the engines were cut off, the ship max speed remained the same and you could end up using more engines then you really had to get that speed...
though that's just off of my own (very) limited experience
and as a new player let me say: 'thanks, and I'll try to make it hard to kill me'
