Please help confirm my heater hose connections

I'm working on my 5.3L LM7 swap and need to know which heater hose is which. I believe the 5/8" hose is the supply (out) to my Vintage Air heater control valve & heater core. This would make the 3/4" hose the return (in) back to the engine from the heater. Is this correct?
