Actually, I have. I've heard "Hold your position" used to mean "stay put", and "hold down the position" used to mean "defend the position". Either way, it doesn't matter, though. That's not the point. I'm not arguing that it doesn't work as a metaphor, or that one is more widely accepted as a metaphor. I'm saying that the British usage of it without the "down" makes no more literal sense than the American usage with the word "down". And anyone saying different is either lying to themselves because of some strange insistence that their colloquialisms are better than our colloquialisms, or lying because they don't want this video that they like to be wrong, or they are just plain stupid.

My point was simply that the word 'hold' has one more definition than you are aware of and thus 'hold the position' does make literal sense whilst 'hold down' does not.
