Once out, it's the right way for the OOD. Notice that I've not had to get the hose over my arm to do this as I would with an 'under arm' routing - just pull the 2nd stage out and stick it in your mouth, nothing else needs to be 'sorted'.
Notice also that there is zero possibility of any entanglement or 'issue' between the octopus hose and my primary hose (which comes over my right shoulder as normal).
