<font color='#000F22'>Hey Lettuce - It's only my opinion.
Yes, buddy should have "ducks in a row" but OOA situation can happen at any time and it might not be my buddy that comes screaming in for air it could be another member of the dive team.
Also - I would advocate not clipping off your primary when you've moved to your deco gas. You buddy could o2 tox and easy access non-deco gas could save his life.
If you're diving the long hose then it shouldn't be waving in the wind but under the right arm, round the neck and hanging in the triangle.
If you want to check that a post hasn't rolled then reach behind and feel for it. Purging is never a good idea in cold water unless you really need to. Also If the post has rolled and you tap the purge it'll flow and you'll think everything is fine - then you'll go to breathe of it and get diddly.
There are many failure possibilities - I was just outlining the most common ones.
All I would say is do whatever you're comfortable with but remember to check the back-up reg on the dive every now and then cos you don't want it failing when you need it. The easiest way to check is to breathe off it.
Again - just my views - not necessarily the right ones!
