It is a rules question. He feels uncertain on the rules, and is asking about it. Hence, a rules question. However, like you said, the rules are actually pretty clear. Technically, that is. The auto-hit is not contradicted anywhere in the rules, so technically there's no ambiguity about it.
But there is a meta-game level ambiguity here. Most players of TI have played other strategy games as well, and quite a few of them always include a chance for success and fail ("1" and "0") . Therefore it is a very valid question to ask if TI also has auto-hit or auto-fail. This is because of the flavor of the game. (Space) battles are emergent and highly chaotic, meaning the outcome is never certain. Even the death star was blown to bits (twice) by punch of lousy rebels. So the flavor (space battle) would indicate that there is auto-hit and auto-fail. To many people having auto-hits is as obvious as fighters needing a carrier.
Sorry for digging up such an old post, but I felt that this matter needed to be pointed out.
