Ian that connection is my recollection of the instructions on the package, although years have passed since. But it makes sense to me: The flow is typically (LS1s etc notwithstanding)
Back of water pump into block Block up into heads Heads into manifold Manifold to top of radiator (inlet) by way of thermostat.
Heater hose from manifold pipes hot water back to heater core, then returns it to the water pump inlet/lower hose spout.
By introducing pressurized water (garden hose) into the heater hose in the manifold, you are reversing the flow of water. It would go into the head, then the block, and out the water pump in reverse flow, then up the radiator and out the filler neck. The cold water keeps the stat closed so it doesn't just run out the top hose.
IF you put it in the other heater hose as you suggest, you are just introducing cold, clean water into the normal flow.
Am I missing something ?
