Normal Mode: The top output jack sends the audio signal to the bottom input jack until a patch cable is inserted. The cable interrupts that signal path and intercepts it, sending it through the cable only.
Half-Normal Mode: The top output jack sends the audio signal to the bottom jack even if you've inserted a patch cable. This lets you split the signal to send to two inputs. The splitting will be interrupted if a cable is patched into the front input, though.
Thru Mode: The top output jacks only sends the signal to each other, back-to-front. Unless you plug in a cable to send the signal to an input, the signal hits a dead-end.
