Flying I has explained very well how to visualise the marshaller's instructions.
In case you are interested, it is done this way because it dates back to the days of multi engined tail draggers which were turned by differential power .... add power to the right engine and you turn left. Even with a trike gear multi, differential power is a very effective way of turning.
I suppose singles have always had to go with the flow!
