Hey Darlo,
You are right in one respect, inverted twins (or 'Twinverts') are used by a goodly number of divers (Hobby, Steve W, Andy2Tanx from these very boards being day-to-day practitioners of the 'art') are used for a number of reasons - here's a couple:
* Personal choice - where that diver has tried other options including 'standard' config twins, but has found that for them, inverting their rig allows the freedom of movement to enact a shut-down and isolation is a hurry. Some divers are simply not happy or comfortable with the standard twin-rig config.
* Military/RE/Royal Navy Diver - these guys dive to rules that any recreational and some tech divers would find simply anathema. They don't get the option to dive in a recreational dive rig as you and I might understand the term, whilst 'on the job'. Mine-clearance, U/w Ex - when not using their rebreathers - all dive using the modified 'twinverts' on most jobs. If ever you get to see the video of the RN re-setting the White Ensign on the wreck of HMS Royal Oak in Scapa Flow (a video I can strongly recomment you all watch), then you will see a number of configs used, but mainly the one above.
There are certain schools of diving which might frown on the use of 'twinverts', but then again, the guys actively diving using the rig are passed caring about what any given diving agency might have to say.
HTH.
