On a one pipe system, does it matter which side the return and intake valves on a rad are?

I have one radiator in my living room, where the return valve gets hot, but the water does not seem to flow up through the intake valve - so the radiator gets very slowly but from the bottom.

Is it possible that the radiator has been fitted the wrong way round, where the return should actually be the intake? Or is that not a thing on a one pipe system?

You could try taking the radiator outside and flushing it out with a hose pipe.

A lot of tall vertical radiators tend to be one way flowing.
