Apples and oranges? I.C engines are all similar in basic designs and designers of all types face the same problems.
Not everybody on this board is a technical genius (I know I certainly am not) and drawing parallells can help get a point across. Whether it is 100% on the nail, isn't relevant to this discussion. The basic principles are.
I have spent many hours with students looking blankly at me when explaining theory, especially in regard to piston engines. Putting the explanation in the context of what people are familiar with helps hugely. If it gets the point across and helps promote understanding, then that's all that matters.
