Maybe it's a language barrier....if your 200 miles out of POM at FL450, radio failure...what are you going to do? No tower, no approach, no center...I guess all the relevant airspace arguments, transitions, clearances just went out the door didn't they?
I personally don't think it's that hard to consider that flying to the IAP, to descend in the procedure (HP) for the approach IS how one would do it.
Of course others would probably descend down to 6k for the IAP, flying through all sorts of traffic, with tower, approach and center, moving all sorts of traffic out of your way. Expect a nice phone call on the ground wondering why you took it upon yourself to descend from your last known assigned altitude...
Anyway...take a look at no radio procedures, last assigned altitudes, clearances and all that, you'll find I am right, that you can and will descend over POM in the hold, as gawd knows what altitude you were last assigned to.
