Depends on who you ask:
Ace Hardware Suspended Ceilings
With the homebuilders I worked with before what constituted a 'suspended' ceiling to them was the ability to remove panels for access to what's behind the ceiling (such as pipe, wire, etc).
Just a variation on terms that all mean the same thing, obviously. Since we build with wood here generally for homes a ceiling like what's shown here would be raised up above the level of the rest of the ceiling and thus be a raised ceiling/vaulted/depending on the builder. I had forgotten that small fact when looking at the photos the first time.
