Your assumption is correct. If you put your finger over the end of the boiler clack pipe then all the pump output should return to the tender without developing any pressure on your finger. A by-pass is “normally” an open and shut valve of some kind, ie flow in and flow out, not a three way diverter with one in and two outs.
