Why is the second diagram (sentence) not "not be a good show -> no sophisticated listeners

Unless introduces a necessary condition and the sentence states "But there will not be a good show unless there are sophisticated listeners in the audience," so why in the answer explanation is it worded as "Sophisticated listeners (no) -> Good show (no)?

Hi,

Our statement is: bad show unless SL. This means that if there are no SL, then we are guaranteed to have a bad show. Or,

If No SL -> No Good Show

The way you diagramed it, (No GS -> No SL/ If SL -> GS) would have some pretty whacky implications. Does having SL guarantee a good show? Maybe the performers are simply such, or the venue is struck by a meteor. In both of these cases it would not be a good show regardless of whether there are SL in the audience.
