rule number one, in a sentence: internally--and that's what we're dealing here--it never "goes to the input"; internally, all signals _always_ flows towards output buses ;)
on MIDI tracks, the audio signal goes to the first defined output bus, being quite usually the one named after "Master Out" by default;
however you may select and choose to any other audio output bus if you prefer--that's exactly the suggestion you followed there;
if you wish to "tap" or "fork" to yet another output bus as well then that's exactly the purpose of an "Aux Send".
