That comment holds true for SAR and, I suspect, HEMS as well.
I agree, having done both.
However, having the man who pays your salary (and who can dismiss you from your hard earned job with a wave of his hand) sitting behind you in the cabin adds a certain extra pressure.
I've never forgotten the story of one pilot who landed on the aircraft owner's lawn on his first day in the job, but slightly in the wrong place. He hadn't been briefed on the
correct place. He was told he was incompetent and never to return.
