So you can pass them in whatever order you like, whenever you like so long as you pass the pertinent info.
RTF Examiners have always required the call to be made in the stated order. I recall the old RTF Written exam where you had to write out the full Distress Message and you lost marks for getting anything wrong including the "wrong" order.
Whilst I agree that at the end of the day the order is not that important, it is basically a Check List and remembering it in the given order aids passing all of the required information when you mind is on other things. The first sign of stress is the wrong words coming out of the mouth.
