Ok. The correction is....
I didn't mean to imply that you said anything wrong... I, like you, found Rauhughes example confusing.
It isn't clear to me if Rauhughes meant that:
A) his Barrel Roll was a tight fit and people disagreed as to whether or not his ship could fit
B) he wanted to Barrel Roll into a position where his ship was "touching" another ship, and therefore could not be shot at by said ship
His use of the word "touching" is confusing, especially since he is trying to point out the technical difference between "touching" and "overlapping".
